Tangled, begging for help, the little brother is grateful.

After being together for a long time, you need to run in the personalities of the two of you. In your case, I think the main thing is that she cares about your performance, otherwise she will be full of food and support, and she will have nothing to do. Maybe you both don't know what the other person wants, and you are using the wrong expression.

You can have a good chat when you have time. If the other party is dissatisfied or needs to be changed, make a list to find out where the problem is, and express your position. I guess that will help.

Are you tangled ? Who doesn't get tangled? It's inexplicable.

How can you not quarrel when you are in love, the next time you quarrel with her, use English, and when she knows what you are scolding, the anger will disappear.

Be sure to ask her what she thinks, if you don't know what she thinks, it's easy to make a big accident.

It's not easy to be together for so long, cherish it, it's okay to accommodate each other, in fact, you think about it, it's a big deal!! Just don't let yourself regret it later

Why is it noisy, because the feelings of junior high school are different from the feelings of you now entering the society, life has become practical, and you didn't think about these trivial things in life when you went to school before, but you have to think about it when you get married, you have to correct your mentality. If you still love her very much, you must learn to endure and learn to adapt, and you should live for a lifetime!

It's about that??

fainted, and I had to say something.

The filter residue must be all copper (excess sulfuric acid can indicate that there is no Fe, Cuo, Fe2O3 in the precipitation, and no copper ions in the solution can indicate that the copper is precipitated);

The solid is copper, which means that there is no Fe3+ in the solution (it has to react with copper), so A is wrong.

Finally, the solid obtained by burning is Fe2O3, in which the mass of the iron-containing element is, so B is wrong.

Iron element mass = , and the original solid is only, so cuo mass does not exceed, so c is wrong.

Since the solute in the final solution is excess H2SO4 and FeSO4, and the amount of iron element = , indicating that the amount of sulfuric acid substances participating in the reaction = containing hydrogen ions, part of which hydrogen ions generate hydrogen, and the other H+ is combined with oxygen in the alloy to form water, because the amount of oxygen in the alloy = (, it combines hydrogen ions, so hydrogen is generated in sulfuric acid, that is, hydrogen is generated, and the standard volume is 448ml, d pair.

The problem can be solved in this way, because the third step does not contain copper, and because it has been treated with sulfuric acid (at the same time, the iron in the sample has been reacted with sulfuric acid, so the volume of hydrogen in the gas can be found according to the relationship between iron and sulfuric acid), then the filtrate is iron sulfate, and after the reaction with sodium hydroxide, it should be an iron hydroxide solid, and after heating, it becomes ferric oxide, so the solid is the formed ferric oxide.

The second step is the mass of the copper in the sample, because the copper never reacts.

At this time, the remaining mass is the mass of (iron, copper oxide, iron oxide), and in the third step, the mass of iron oxide produced by burning can be found by using the mass of iron oxide produced by burning, and the mass of iron sulfate (m) can be found, but the iron sulfate at this time is the sum of the reaction between iron and sulfuric acid, and the reaction of iron oxide and sulfuric acid is the sum of the reaction between iron and sulfuric acid, so the mass of iron sulfate produced by the reaction of iron and sulfuric acid is x, and the mass of iron and ferric oxide can be found according to their relationship.

And because in all reactions, only iron reacts with sulfuric acid and has hydrogen, so according to the mass known above, you can find the volume of hydrogen under the standard condition...

So the volume of the gas is calculated, and the mass of each substance is calculated.

A: Because filtrate A does not contain Cu2+, Cu exists in the form of elemental substance, that is, filter residue. CU cannot coexist with FE3+.

B: Due to the excess of dilute sulfuric acid and the presence of Cu, Fe2+ exists in Fe solution. A sufficient amount of NaOH was added to generate Fe(OH)2, and the solid formed by full burning after filtration was Fe2O3, and the mol mass was 160, and the Fe mass was calculated.

c: The filter residue is copper element, and the amount of the substance is. If CU is all from CUO, then there is no reducing agent to talk about Fe3+ reduction.

If the situation is true, and there are relevant materials, the insurance company must refund the money, of course, as for the form of the apology, it depends on the actual situation, but when you mentioned the surrender, the staff only needs a copy, does not provide any proof of surrender later? If the staff does not give you written information, it is a violation of the law, and if you do not have written information in your hands, you will lose the initiative, however, your details will be retained in the customer system of Ping An Insurance, and you can go to the front desk to inquire in person.

However, you also mentioned that a total of 62 yuan was deducted, I don't think there is any need for this compensation, just refund it, and there are so many service staff, it is not easy to find out who made a mistake, the waiter at the front desk can say sorry for the wrong person, you say. I'm also in the service industry, and it's not easy to know this kind of person. Because it's not worth it to be angry.

1. Specific analysis of specific problems. But the compensation is certain (you have losses).

2. If the other party is sincere, then good, this matter is over, more things are better than less things. 3. If the other party has a bad attitude, you have the right to ask the relevant person in charge of the insurance company to apologize.

4. In fact, in this case, the person in charge will take the initiative to apologize to you and calm your anger haha.

It is an internal service error of the insurance company, and the insurance company service ** complains about the above situation. If you are not satisfied with the results, you can call the local insurance regulatory bureau** to complain!

Don't understand what you're doing? Build a new simulator?
