The equation shows the reaction between zinc metal and hydrochloric acid.

kodGreya [7K]

Answer: 10 grams of Hydrogen gas will be produced theoretically.

Explanation: The equation for the reaction between zinc metal and hydrochloric acid is:

$Zn(s)+2HCl(aq.)\rightarrow ZnCl_2(aq.)+H_2(g)$

As HCl is present in excess, therefore limiting reagent is Zinc metal as it limits the formation of product.

By stoichiometry,

1 mole of Zinc metal produces 1 mole of Hydrogen gas, therefore

$\text{5 moles of Zinc metal will produce}=\frac{1}{1}\times 5=5\text{ moles of Hydrogen gas}$

Amount of Hydrogen gas produced can be calculated by:

$\text{Mass of gas produced}=\text{Moles}\times \text{Molar mass}$

Molar mass of Hydrogen = 2 g/mol

Mass of hydrogen gas produced = (5 moles )× (2 g/mol)

Mass of hydrogen gas produced = 10 grams
