Question

question 5 of 10
the chemical reaction that occurs when gasoline and air are ignited is called
a(n) _____.

a. decomposition reaction
b. acid - base reaction
c. combustion reaction
d. dehydration reaction

Explanation:

To solve this, we analyze each option:

• Option A: Decomposition reactions break a compound into simpler substances; gasoline ignition isn't this.
• Option B: Acid - base reactions involve acids and bases (like H⁺ and OH⁻ transfer); gasoline and air don't fit.
• Option C: Combustion reactions are exothermic reactions where a fuel (gasoline) reacts with an oxidant (oxygen in air) to produce heat, light, and products like CO₂ and H₂O. This matches the ignition of gasoline and air.
• Option D: Dehydration reactions remove water from a compound; not related to gasoline ignition.

Answer:

C. combustion reaction
