A metal oxide reacts with hydrogen to form the metal and water. All the reactants are converted into products.
| Reactant | Mass of reactant in g | Product formed | Mass of product in g |
|---|---|---|---|
| Metal oxide | 10.00 | Metal | 8.00 |
| Hydrogen | 0.25 | Water | 2.25 |
Use the data to explain which reactant is reduced and which reactant is oxidised.
