Question

H2 + O2=...Fe2O3 + H2 = Fe0+H20H20=...MnO + H2=Mp+...FeO+H2 = Fe+...​

Answer 1

2h2+o2=2h2o

2fe2o3+2h2=4feo+2h2o

2h2o=2h2+o2

mno+h2=mn+h2o

feo+h2=Fe+h2o

Answer 2

It seems like you have provided a series of chemical reactions with some missing information. I'll try to fill in the missing parts for you:

1. H2 + O2 → 2H2O (Combustion of hydrogen gas and oxygen gas to form water)

2. 3Fe2O3 + H2 → 2Fe + 3H2O (Reduction of iron(III) oxide with hydrogen gas to form iron metal and water)

3. 3MnO2 + 4H2 → 3Mn + 4H2O (Reduction of manganese(IV) oxide with hydrogen gas to form manganese metal and water)

4. 2FeO + H2 → 2Fe + H2O (Reduction of iron(II) oxide with hydrogen gas to form iron metal and water)
