What volume of hydrogen will be obtained by the reaction of hydrochloric acid and 1.12 g of iron in the substitution reaction?
To solve this problem, we write down the reaction equation: 2Fe + 2HCl = FeCl2 + H2
n (Fe) = 1.12 g / 56 g / mol = 0.02 mol.
According to the equation n (H2) = 1/2 n (Fe)
0.01 mol * 22.4 l / mol = 0.224 liters of hydrogen
