Which gas is produced when an acid reacts with a metal? (2023) 2023
Step 1: Identify the acid. An acid is a substance that can donate a proton (H+). Common examples include hydrochloric acid (HCl) and sulfuric acid (H2SO4).
Step 2: Identify the metal. A metal is a solid material that is typically hard, shiny, and a good conductor of heat and electricity. Examples include zinc (Zn) and magnesium (Mg).
Step 3: Understand the reaction. When an acid comes into contact with a metal, a chemical reaction occurs.
Step 4: Know the products. One of the products of this reaction is hydrogen gas (H2).
Step 5: Conclude that hydrogen gas is produced. Therefore, when an acid reacts with a metal, hydrogen gas is released.
