Answer 1

Answer: The coefficient of [tex]H_2O[/tex] in the balanced chemical equation is 4.

Explanation:

Every balanced chemical equation follows Law of conservation of mass.

This law states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form. This also means that the total number of individual atoms on the reactant side will be equal to the total number of individual atoms on the product side.

For the given balanced chemical equation:

[tex]Fe_3O_4+4H_2\rightarrow 3Fe+4H_2O[/tex]

The coefficient of [tex]H_2O[/tex] in the balanced chemical equation is 4.

Answer 2

Final answer:

The coefficient of H2O in the balanced chemical equation Fe3O4 + H2 ⟶ Fe + H2O is 4.

Explanation:

The coefficient of

H

2

O to balance the equation in terms of mass and charge.

The student asked about the coefficient of H2O in the balanced equation Fe3O4 + H2 → Fe + H2O. When balancing this equation, we must ensure that the number of atoms of each element is equal on both sides of the reaction. Balancing iron (Fe) and oxygen (O) first, we find that the balanced equation is Fe3O4 + 4H2 → 3Fe + 4H2O. So, the coefficient of H2O in the balanced equation is 4.
