You don't even know about this ? As long as you learn to empathize it can be solved. You don't want to complicate him, for example, I'm looking at your train of thought now, you want to be a host, no one objects, everybody supports it, but you know what you have to learn to be a host? 1

Understand. Learn about 2Transposition 3

Emotions 4Eyes 5Tone 6

Atmosphere Here's my answer to youUnderstand. Understand (give you an event, you want to speed understanding, digesting, understanding the content) 2

Transposition (you have to think about what the consequences of what you say in the empathy of speed, such as: you said that China is going to KP with Japan, see if this topic can attract the audience, if you are the audience, can this topic attract your attention) 3Emotions (you have to follow the audience's emotions to see yourself, you have to keep them at any time, you have to combine emotions, you have to learn to cooperate) 4

Eyes (a good host can see whether he is qualified or not) 5Tone (to give the audience a phenomenon that you are always saying is right, the tone of speech depends on what factory you are talking in. See people and talk to people.

Hell talking nonsense) 6Atmosphere (Not much to say.) Not much.

You ask me what inspired meDon't grow old and rely on others.

1.I didn't expect that the old man would be so expectant of our arrival, but we didn't believe it, and we couldn't fulfill his little wish until the old man died. 2.

words, deeds, occupation; Kind, attentive, lonely. 3.The old man misses and looks forward to us very much.

4.We can't let those lonely old people be lonely again, and we don't want to neglect the elderly for the sake of work.

I think it's too colloquial!

Some are few, and there is no beginning and end, and if the name of the elf is not very good, it is wishful or as expected.

This can't be, at least in the 23rd century, at that time...

1. The multiple of the previous number is equal to the number of the following, so the number of air is 2, 300 per day, and the total number of 15 days to complete is = 300 * 15 = 4500 is actually a multiple of the original plan So 300 * is produced every day

It took 4500 450 = 10 days.

3,750 units per day, so 250 units per day are planned.

The actual is 250*2=500

So it took 3750 500 = days.

Second question Answer: 300 15 [300 days] Answer: It took 10 days.

The answer to the third question: 3750 [3750 15 2] = days] Answer: It took days.

300 times 15 equals 4500, 300 times equals 450 and 4500 divided by 450 equals ten days.

France Pavilion The queue is fast

The Belgian Championship Japan Pavilion is very distinctive, so it is necessary to shoot for a long time

Now you can go to the city case pavilions in Spain and Denmark to get stamped (you want to buy an Expo passport, which is sold in licensed shops inside and outside the park), and you can go straight in without queuing.

The Italian Pavilion is very distinctive

Good shopping at the United Africa Pavilion

You can not see the Chinese Pavilion, it should not be demolished, and you can go to see it in the future, and there are many distinctive small restaurants that you can choose to see

There are a lot of people, and it is recommended to line up reasonably if you can't see much in a day.

Good luck

Thailand Pavilion, Swiss Pavilion has a cable car is very interesting, but there is a long queue, Saudi Arabia Pavilion, Germany Pavilion, the United States Pavilion can also be, more novelty is, these pavilions you have to see, a day is estimated to be enough, you can go to ask which museum has activities today, or that pavilion is open, there are activities, the opening is very fun.

I don't know if you're out of town or local, so it's convenient to talk about it, this is not something that can be said at a little bit.

There are also many pipes on the 2nd floor that are inactive, and you are past the expiration date.

Taiwan Pavilion, China Pavilion, Hunan Pavilion, and some foreign ones, most of them are OK, but they are too expensive to buy.

Swiss Pavilion, Saudi Arabia Pavilion, Italy Pavilion, France Pavilion, Germany Pavilion, Poland Pavilion.

Blank space is best, if you add any text or drawing, it will make the picture unbalanced and cluttered.

There are often some gaps in our hand copying newspapers, and the emptiness is too ugly.

I can teach you something.

1.Add some famous quotes to a larger gap.

2.Spend a little bit of a flower in the middle of the void or something.

Search for Dogs first, then open the home page, type the **and**format you need in Dogs,Then**to the folder of the disk you need,Finally, you can look at it,It is recommended to use Thunder**。

The team will answer for you

1) The 2NO+O2=2NO2 reaction can be carried out spontaneously at room temperature, and it is obvious that the decrease in the number of moles of gas is an entropy reduction reaction, so that the enthalpy of the reaction must be negative, that is, the reaction is exothermic.

2）fe+s=fes。When the reaction emits a large amount of heat, blue-purple flames, it produces a black-brown solid. In the laboratory demonstration, a red-hot glass rod is used to contact the mixed powder, and then the glass rod is removed, and the reaction proceeds spontaneously completely, indicating that the reaction is exothermic.

3) Many exothermic reactions do not proceed spontaneously at room temperature because they do not reach enough temperature to make the reactant molecules and atoms enter the activated state (i.e., active), and once the reaction starts, the heat released will make the ambient temperature of the reactants higher than the temperature required for activation, although the heat will be lost, but the heat released is enough to maintain the temperature required for the reaction, so that the reaction continues to proceed spontaneously, just like the reaction in (2).

1.It is really difficult to say that different states and different reaction pathways (e.g., catalysis) will run out different proportions of nitrogen oxides"people"

I'll give you some NOx δH0, practice writing out various reactions that don't use NOx, and then calculate δH after equilibrium

Example: 2NO + O2 --2NO2

h=2*negative exothermy.

2.I didn't find the sulfide δh of iron, so I'm sorry, but I guess it's exothermic.

3.Whether the reaction can be spontaneous or not, you don't just look at δh, you have to see whether the free energy δg is negative, if it is not negative, it will not happen.

Any reaction will eventually reach the minimum of free energy.

Free Energy Definition:

dg = d(u - ts + pv) = sdt + vdp + other forms of work (e.g. work of chemical energy).

Where: du = dq + dw = tds + pdv + dn

ds = dq/t

1 2NO2 + O2 = 2NO2 exothermic.

Formula: Fe + S ==Fes

Exothermic, that is, because it is an exothermic reaction, it is ignited back and the reaction proceeds spontaneously.

Reflection: Iron powder and sulfur powder are mixed well, heated to red heat at one end, and stop heating; Until the whole mixture is red hot and forms a black lumpy! The temperature of the object when it is red hot is 600 degrees Celsius.

Because the heat released in the reaction guarantees that the reaction will continue.

NO+O2==2NO2, exothermic.

2. Fe+S=Fes, the reaction requires thermal conditions, and the red-hot glass rod contact mixture is to heat the reaction of the iron-sulfur mixture to achieve this condition. Just as the combustion of white phosphorus in warm water with oxygen is an exothermic reaction, but the ignition point of white phosphorus needs to be reached first (warm water is to achieve this condition), after the glass rod is removed, the reaction between iron and sulfur is violently carried out and turns into a red-hot state, which can be seen that the reaction is an exothermic reaction.

3. The heat emitted by the reaction is enough to maintain the energy required for the reaction, so the reaction will continue.

2NO+O2=2NO2 Exothermic.

Fe+S=Fes Exothermic reaction Thermal conditions are required, and the red-hot glass rod in contact with the mixture is to stop heating the reaction of the iron-sulfur mixture to this condition. Just as the extinguishing of white phosphorus in warm water with oxygen is an exothermic reaction, but it is first necessary to reach the ignition point of white phosphorus (warm water is to reach this condition), and after the glass rod is removed, the reaction of iron and sulfur stops violently and becomes red-hot, which can be seen as an exothermic reaction.

This can help you so much, I hope to forgive me.

(1) 2n0 + oxygen = 2n02 reaction endothermy.

2) Fe+S=Fes Iron powder and sulfur powder are mixed well, heated to red hot at one end, and stop heating; Until the whole mixture is red hot and forms a black lumpy!

3) The absorption and release of heat of the reaction are related to the energy of the reactants and the products, or the energy of endothermy from bond breaking, and the energy released by bonding, when the total energy of the reactants is higher than the total energy of the products, the heat is released, and when the total energy of the reactants is lower than the total energy of the products, the heat is absorbed.

1.The reaction under discharge conditions produces nitric oxide, which is often directly oxidized by oxygen to nitrogen dioxide. The reaction is endothermic.

2.Exothermic, high temperature conditions are required.

3 Because less heat is lost than the heat emitted by the molecule that is reacting.
