How much hydrogen reacts with 32 g of iron oxide (2).
August 17, 2021 | education
| 1. Hydrogen reduces pure iron from its oxide by the reaction:
H2 + FeO = Fe + H2O;
2.find the amount of oxide by the formula:
n (FeO) = m (FeO): M (FeO);
M (FeO) = 56 + 16 = 72 g / mol;
n (FeO) = 32: 72 = 0.44 mol;
3.the chemical amounts of hydrogen and iron oxide (2) are related as 1: 1, that is:
n (H2) = n (FeO) = 0.44 mol;
4.Calculate the volume of consumed hydrogen in terms of the molar volume constant:
V (H2) = n (H2) * Vm = 0.44 * 22.4 = 9.86 dm3.
Answer: 9.86 dm3.
