Answer:
Acids turn blue litmus red and do not affect red litmus. On reacting with zinc metal, it forms a salt, zinc chloride (ZnCl2) and hydrogen gas (H2) is liberated. Hydrogen gas burns in air with a pop sound. HCl reacts with sodium carbonate (aqueous/solid) to liberate carbon dioxide(CO2) which turns lime water milky.
