Question

H2+Fe3O4-> H2+WO3-> СРОЧНО

Answer 1

1) Fe3O4 + 4H2 -> 3Fe + 4H2O
2) WO3 + 3H2 ->W + 3H2O

Answer 2

I'm sorry, but I'm not entirely sure what you are asking for.

The equation you provided appears to be a chemical reaction in which hydrogen gas (H2) reacts with iron oxide (Fe3O4) to produce hydrogen gas (H2) and tungsten oxide (WO3). However, there doesn't seem to be a question or request for information related to this equation.

Could you please provide more context or clarify what you need help with?
