Question

Write chemical equations to show what happens when an acid reacts with a metal; also write the name of the main product formed.

Answer 1

When an acid reacts with a metal, it produces a salt and hydrogen gas.

General Equation: \[\ce{Acid + Metal → Salt + Hydrogen gas}\]

Example: \[\ce{Zn + 2HCl−>ZnCl2 + H2 ^}\]

Zinc reacts with hydrochloric acid to form zinc chloride (a salt) and hydrogen gas.

Main product formed: Zinc chloride (ZnCl₂)
