What s going on with the recent sharp drop in gasoline prices in most cities in China

1) Detect the presence of CO, CO2 and H2O in ethanol combustion products, CO can be hot copper oxide, according to the change of solid color; Carbon dioxide can be tested with clarified lime water to see if it becomes turbid; Inspect the water with anhydrous copper sulfate to see if it turns blue; When there are all three, the presence of water vapor should be tested first, because when verifying the existence of carbon dioxide and carbon monoxide, it is necessary to pass through the solution, which can bring out the water vapor; Then test the carbon dioxide, and finally remove the carbon dioxide, and then check the carbon monoxide according to the solid color change and the product, so the order is So the answer is: 2) according to the carbon dioxide, the clarified lime water can be made turbid, the sodium hydroxide reacts with carbon dioxide, and the carbon dioxide can be absorbed, and the lime water in bottle A in the device becomes turbid is to test carbon dioxide, sodium hydroxide in B is to absorb carbon dioxide, and the lime water in bottle C is to test whether carbon dioxide is removed; Therefore, the answer is: verify the existence of CO2; Removal of CO2 from gas mixtures; (3) and cooperate to test carbon monoxide, according to the color change judgment may contain carbon monoxide, and carbon monoxide oxidized into carbon dioxide, and then used to further confirm that the generation is carbon dioxide, so the contained is clarified lime water, prove that the combustion product contains co, the experimental phenomenon is no obvious phenomenon in c, and the clarified lime water becomes turbid, so the answer is:

clarified lime water; There is no obvious phenomenon in c, and the medium clarified lime water becomes turbid; (4) First, the existence of water vapor is tested by anhydrous copper sulfate, because when verifying the existence of carbon dioxide and carbon monoxide, it is necessary to pass through the solution, which can bring out the water vapor and affect the determination of water vapor; So the answer is: anhydrous copper sulfate; Water vapour;

According to national news, a new round of refined oil price adjustment window will be opened at 24 o'clock today (April 15). The specific situation of this oil price adjustment is as follows: gasoline is reduced by 545 yuan per ton, and diesel is reduced by 530 yuan per ton.

This adjustment is the first ** reduction in 2022, and oil prices have been stranded in 2022 after 6 rises, 1 drop and 0 falls.

The National ***** Monitoring Center expects oil prices to remain sharply in the short term. In the future, it is necessary to focus on the statement and progress of Europe's energy sanctions against Russia. Affected by the conflict between Russia and Ukraine, the current Russian ** production fell to 10.3 million barrels per day from the level of 11 million barrels per day in March, and the International Energy Agency expects that Russia's output will fall by 1 million barrels per day in April and a sharp drop of about 3 million barrels in May.

It remains to be seen whether this gap can be filled, and it is the main uncertainty affecting oil prices.

On October 29, Xie Zhenhua, deputy director of the state, said that in the current situation of coal, refined oil and grain, the country will make some adjustments in a timely manner according to the overall economic and social development. Since then, it has been reported that the relevant departments have recently drawn up three ** reduction plans, which are 500 yuan, 800 yuan or 1,000 yuan per ton of retail price of refined oil, that is, about yuan, yuan and yuan per liter of refined oil. Subsequently, many experts said that oil prices will be lowered in November.

According to the data, in October 2006, the international oil price was around $60 per barrel, and the retail price of No. 93 gasoline in China was one yuan liter at that time, but now, the international oil price has fallen back to about $60 per barrel, but China's No. 93 gasoline is already above six yuan per liter.

Why has oil prices not come down? Qi Fang, vice president of the Petroleum Chamber of Commerce of the All-China Federation of Industry and Commerce, revealed in an interview that he would listen to the opinions of the two major groups of PetroChina and Sinopec when adjusting oil prices, so when international oil prices change, the two groups can effectively influence the price adjustment policy.

Affected by the international ****, the state has regulated oil prices, in order to alleviate everyone's economic pressure.

It's because after the National Day, everyone doesn't go out much, which has a lot of impact on the demand for cars, and the market is not so big.

This is due to the international market and has nothing to do with the National Day.

With the improvement of living standards, almost every family has its own means of transportation, including a speeding car, a speeding motorcycle, a light and convenient electric car, or a leisurely bicycle. And for those of you who have a car at home, the most important thing you are concerned about must be the price of oil.

Don't rush, it will rise soon.

Because of the war in Libya, which affects international oil prices, Chinese oil giants need to bring oil prices into line with international oil prices. So it went up. When the price of oil is **, China's oil majors will be derailed.

Because the rate of change in the three places has exceeded 4% for more than 22 consecutive working days. If the conditions are met, the price can be adjusted.

It's all the fault of the monopoly industry.

If the price of gasoline does not rise, what kind of corruption do the uncles of Sinopec and PetroChina use?

China's National Development and Reform Commission released a message on the 19th, according to the changes in oil prices in the international market, in accordance with the current situationRefined oil** Formation mechanism, since 24 o'clock on the 19th, domestic gasoline and diesel ** per ton will be reduced by 95 yuan (RMB, the same below) and 90 yuan respectively.

Equivalent to the price increase, the national average, No. 92 gasoline and No. 0 diesel per liter were reduced by yuan and yuan respectively. This is a domestic refined oilRetail LimitThe fourth downward revision of the year.

Zhuochuang Information Refined Oil AnalystXu Leisaid that after the implementation of this reduction policy, taking a small private car with a monthly run of 2,000 kilometers and a fuel consumption of 8 liters per 100 kilometers as an example, before the next price adjustment window opens (24 o'clock on December 3, 2021), the cost of consumer fuel will drop by about 5 yuan.

In the logistics industry, the fuel consumption of 10,000 kilometers per month is 38 liters per 100 kilometersSteyr Heavy Duty TrucksFor example, before the next price adjustment window opens, the fuel cost of a single vehicle will be reduced by about 142 yuan.

The international **** is in a weak range** downward trend. Xu Lei said that on the one hand, the market is worried that if major economies such as the United States release strategic petroleum reserves, it will increase in the future. On the other hand, the number of new crown infections in some European countries has rebounded, which may curb oil demand, and there is a risk of excess supply and demand.

Looking ahead, Gao Qingcui, a refined oil analyst at Zhuochuang Information, said that OPEC+ and some oil producers continue to reiterate a moderate increase in production, and the expectation of tight supply and demand may give strong bottom support to oil prices. However, because there are still many uncertainties about the release of strategic reserves by the United States, the international in the near futureOil pricesOr maintain the trend of **, the next round of gasoline and diesel retail price limit is expected to be lowered.

Since the beginning of this year, China's retail price limit for refined oil has gone through 22 price adjustment windows, of which 14 have been raised, 4 have been lowered, and 4 have been stranded. Standard gasoline and diesel were raised by 1,905 yuan and 1,835 yuan per ton respectively during the year, which is equivalent to an increase in price, with a cumulative ** yuan per liter for No. 92 gasoline and a cumulative ** yuan per liter for No. 0 diesel. Compared with the beginning of the year, consumers need to spend 75 yuan more to fill up a 50-liter tank of No. 92 gasoline, and the cost of travel has risen.

Because many countries will further release ** stocks, it will further lead to lower oil prices.

Whenever we talk about oil prices, many people always complain that oil prices have been **, but there has never been **. The reason why this situation occurs is actually related to **** around the world. The market itself belongs to the international market, and when the market is further, we can see the situation of oil prices.

First, oil prices may usher in a big price reduction.

Oil prices are related to everyone's daily travel, and when the price of oil is **, our travel costs will increase further. After nearly a year of oil prices, it is likely that oil prices will usher in a significant reduction at the end of the year. Some people say that oil prices may fall by 5% to 10%, and some people say that oil prices may drop by about 2 yuan.

Second, the reason for the price reduction of oil prices is mainly due to the fluctuation of the market.

The main reason for this is that the entire country of the world will release their own ** stocks at the end of the year. When the price of inventory is further reduced, this will further impact the market itself. If the market price is lowered, the price of oil will naturally decrease.

At the same time, when the development of various new energy materials is further, many people are also calling for a drop in oil prices, and the decline in oil prices has almost become an inevitable trend. <>

Third, oil prices may appear short-term.

Before the sharp drop in oil prices, the price of oil in the ** market has actually seen a large decline. Before that, **of** had even rushed to 90 dollars per barrel. After this time, the ** of the drug was generally maintained at about $60 to $70.

AlthoughHowever, the ** of all kinds of commodities is constantly **, in oil prices as the king of bulk commodities, many countries are strictly controlling their own oil prices, but also do not want oil prices to be excessive. To some extent, the decline in oil prices is not necessarily a good thing, because oil prices themselves are not at a high level, which will further affect the overall market development in the long term. <>

Oil prices may usher in the biggest price reduction this year, and the main reason for the price reduction is the **** of international oil prices and the recurrence of international epidemics.

Oil can be said to be related to the international people's livelihood, at present, oil prices are still at a high level, in October this year, there is still a shortage of diesel at gas stations in some parts of the country, wholesale is more expensive than retail, there are many truck drivers queue up can not receive oil, seriously affecting their normal life. This time the price of oil is a boon for drivers of small cars and trucks, and I hope that everyone can seize the opportunity to fill their fuel tanks, so that they can better protect their money bags.

1. What factors are related to oil prices**?

Because of the uncertainty of the international epidemic and the adjustment of international oil prices, which has led to the occurrence of ** oil prices, in order to better avoid the recurrence of the epidemic, countries should take restrictive measures to better control oil prices. The uncertainties affecting oil prices have increased significantly, and oil prices may intensify in the later period, so in order to better protect the safety of your property, you can choose to fill up your fuel tank when the oil price is **.

For oil prices, it is beyond the control of ordinary people. But as a car driver, before refueling must understand the relevant knowledge, it is best to choose to go to a regular gas station to refuel some small gas stations, although the price of oil is lower, but the quality of the oil can not be guaranteed, I hope every driver can realize this. Be sure to strictly follow the traffic rules while driving to avoid traffic accidents.

3. What is my personal opinion?

I believe that the change in oil prices is inseparable from the international epidemic, and the current restrictive measures adopted by various countries will still have a certain impact on oil prices in the later period. The oil price market may pay more attention to the spread of the new coronavirus variant, and international oil prices may bottom wide**, so as ordinary people, we must pay attention to international news in time.

Oil prices may usher in the biggest price cut this year, the reason behind the US oil production is sharply**, coupled with the global recession has led to a decrease in demand in Asia, oversupply, resulting in an imbalance between supply and demand, and oil prices**.

It may be because this year's oil prices are more expensive, or it may be that this year's oil prices are more scarce, or it may be the problem between this year's fuel **, or it may be that the competition from foreign countries is very fierce this year, resulting in a decline in fuel **, so it will lead to such a big drop in oil prices.

Because the amount of **** on the market is very sufficient, this will cause some ** decline, and people can afford it.

The rise and fall of the automotive market is affected by a variety of factors, and market changes are often uncertain. Normally, after the end of the car price reduction, the car market will return to normal supply and demand, ** may also recover, but there will not necessarily be a retaliatory price increase.

In addition, with the development of new energy vehicles, changes in the future automobile market may also bring different trends. The specific situation also needs to consider factors such as market supply and demand, policy changes, and competition patterns.

First, changes in consumer demand

Consumers' demand for cars is changing, and more people are beginning to pay attention to environmental protection and energy saving issues, and are willing to buy new energy vehicles. In addition, the maintenance cost of fuel vehicles is also relatively high, so some consumers choose to buy ** lower used cars.

Second, policy pressure.

It has made it clear that it wants to promote the development of new energy vehicles, and in order to achieve the emission reduction target, ** is introducing various incentive policies, such as purchase subsidies, tax reductions and exemptions, etc. At the same time, it is also strengthening restrictions on traditional fuel vehicles, such as promoting new energy vehicles, restricting vehicles from entering the city, and so on.

3. Competitive pressure.

The automotive market is highly competitive, and various manufacturers are competing for market share. At present, the sales of new energy vehicles are rising, while the sales of traditional fuel vehicles are gradually declining. In response to this situation, some fuel vehicle manufacturers have reduced prices** to increase sales!

Therefore, the main reasons for the price reduction of fuel vehicles are policy pressure, competitive pressure and changes in consumer demand. Over time, these pressures and challenges are likely to increase, and sales of ICE vehicles are likely to continue to decline.

Finally, I want to say that although the price of cars has dropped significantly, as ordinary people, there is no need to blindly buy a car, and you should choose according to your own needs, so as not to spend money, and finally the car is idle and useless, which is actually a waste.
