Mg\(_2\) + 2HCI\(_{(aq)}\) → MgCI\(_{2(g)}\) + H\(_{2(g)}\).

From the equation above what mass of hydrogen would be produced if 12.0 g of magnesium reacted completely with dilute hydrochloric acid? (H = 1, Mg = 24)

The correct answer is A ... mole of Mg = 12/24 = 0.5 mol ,,

Mass of hydrogen = 0.5 × 2 = 1g

If 24grammes of magnesium produces 2g of hydrogen gas then 12g of Mg will produce 1g of hydrogen.
