Question

3Fe + 4H2O <=> Fe3O4 + 4H2

Answer 1

1)
4 molecules of Hygdrogen is produced.


2)
4 atoma of Oxygen is produced.

3)
1 molecule of Fe3O4 is formed.

4)
1mole of 3 Fe : mole of 4 H2O

3 :4
=3/4


5) There are 2×4 = 8atoms of hydrogen on Reactant side.

Answer 2

3Fe + 4H2O <=> Fe3O4 + 4H2
