The state controls smog and coal burning, who can provide several energy saving and environmentally

According to the inscription, s=110m2, the height of the house h is generally 3m, and the air quality in the house room is:

mAir = air sh=, the amount of heat absorbed by the air when the room temperature rises by 10:

Q suction = c air m air t = ?429kg 10 = q put = q suck, and q = mq get:

m=qq==so choose b

The haze weather is mainly caused by the extensive development mode, the unreasonable industrial structure and energy structure, and the root cause is still in fossil energy, one is burning coal, the other is fuel oil, and the other is relatively extensive in the development mode, emitting a large number of pollutants. On September 10, 2013, the "Air Pollution Prevention and Control Action Plan" has been issued, which is the "10 articles of the atmosphere" in the society. We have adopted 35 measures to divide the tasks into key areas and units.

I believe that with the further implementation of the "10 Atmospheric Measures", in 5-10 years, in accordance with the requirements of the "10 Atmospheric Articles", the situation of air pollution will be improved. In fact, the ultimate goal of taking so many measures is to solve the problem of air quality improvement, the first is to reduce coal, the second is to control the car, the car control is actually to reduce the consumption of oil resistance of the stone bucket, the third is to reduce dust, if these measures are implemented in place, the air quality will be improved.

(1) Natural gas combustion produces carbon dioxide and water, and the chemical equation of the reaction is: CH4+2O2

Igniteco2+2h2o

2) The number of years of natural gas energy exploitation in China is: 100 million cubic meters 40.8 billion cubic meters = 57 years, so fill in: 57

3) Photosynthesis of green plants absorbs carbon dioxide, and respiration releases carbon dioxide, so fill: photosynthesis; Breathe

According to the law of conservation of mass, it can be seen that an X contains one nitrogen atom, four hydrogen atoms, and one chlorine atom with the chemical formula NH4Cl

a. Develop new energy; b. Reduce the amount of fossil fuel burned; c. Afforestation can reduce carbon dioxide in the atmosphere Therefore, fill in: ABC

Coal burning produces a lot of carbon dioxide, which causes the greenhouse effect, so right;

Fossil fuels are currently the main energy source** and cannot be banned from use, so wrong;

Plants can absorb carbon dioxide through photosynthesis, and prohibiting indiscriminate logging is conducive to controlling the greenhouse effect, so it is correct;

The development of hydrogen energy reduces the use of fossil fuels and thus CO2 emissions, so right;

The use of hydroelectric power reduces the use of fossil fuels and thus reduces carbon dioxide emissions, so right;

Plants can absorb carbon dioxide through photosynthesis and plant flowers and trees, which is conducive to controlling the greenhouse effect, so it is correct

What is practical in the measures is:

So choose A

(1) From the microscopic diagram of the reaction, it can be seen that the reaction is composed of a single substance and a compound to generate another element and another compound, which belongs to the displacement reaction;

From the microscopic schematic diagram of the reaction, it can be seen that this reaction is: C+H2O high temperature. CO+H2, so the ratio of the number of molecules produced by this reaction is 1:

1 (2) From the law of conservation of mass, it can be seen that there are 4 nitrogen atoms, 12 hydrogen atoms, 6 oxygen atoms in the reactant, and 12 hydrogen atoms and 6 oxygen atoms in the product, and only 4 nitrogen atoms are missing, so the other product is nitrogen, so the chemical equation of NH3 combustion reaction is: 4NH3+3O2

Ignite6h2o+2n2．

Therefore, the answer is: (1) The ratio of the number of molecules of CO to H2 in the displacement reaction is 1:1 (2)2N2
