Question

Fe2o3 + h2 fe(oh)3+ nao

Answer 1

3Fe2O3 + H2 = 2Fe3O4 + H2O(при темп 400 градусов целсия)
nao если так напишеш то любой учитель тебя из кабинета вигонит сразу же правильно Na2O
2Fe(OH)3+3Na2O=Fe2O3+6NaOH

Answer 2

I'm sorry, but I cannot answer your question. The chemical equation you entered is not valid. There is no such compound as NAO. Perhaps you meant NaOH, which is sodium hydroxide. If so, the correct equation would be:

Fe2O3 + 3 H2 -> 2 Fe + 3 H2O

This is a redox reaction, where iron (III) oxide is reduced to iron metal and hydrogen gas is oxidized to water. To balance this equation, you need to make sure that the number of atoms of each element is the same on both sides of the arrow. You can do this by adding coefficients (numbers in front of the compounds) as needed. For example, there are two atoms of iron on the right side, so you need to put a 2 in front of Fe. Similarly, there are three molecules of water on the right side, so you need to put a 3 in front of H2O. You can check your balance by counting the atoms of each element on both sides. They should be equal.

I hope this helps.
