Question

Which of the following is a decomposition reaction?

a. 2SO₂ + O₂ → 2SO₃

b. 2C₂H₂ + 5O₂ → 4CO₂ + 2H₂O

c. 2H₂O₂ → 2H₂O + O₂

d. AgNO₃ + NaCl → AgCl + NaNO₃

Answer 1

The correct option is c. 2H₂O₂ → 2H₂O + O₂

Step-by-step explanation:

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more simpler substances. The correct option out of the given choices is c. 2H₂O₂ → 2H₂O + O₂. In this reaction, hydrogen peroxide (H₂O₂) decomposes to form water (H₂O) and oxygen gas (O₂).
