Question

12 g of magnesium reacts with excess of hydrochloric acid (HCL). The volume of H2 gas liberated at STP is ( Atomic Mass of Mg =24 u)​

Answer 1

Answer:

Mass 24) on reacting completely with acid gives hydrogen gas, the volume of which at STP would be. ∴12g Mg evolves H2 at STP 22.424×12=11.2L at STP.
