Question

question 2 of 10
what are all the products of a hydrocarbon combustion reaction?

a. oxygen, a carbon - based molecule, and heat
b. carbon dioxide, water vapor, and heat
c. hydrogen, carbon, and oxygen
d. carbon dioxide, oxygen, and water

Explanation:

Hydrocarbon combustion is the reaction of a hydrocarbon (compound of C and H) with oxygen. The general equation is \( \text{hydrocarbon} + \text{O}_2
ightarrow \text{CO}_2 + \text{H}_2\text{O} + \text{heat} \). Option A has oxygen (reactant, not product) and a carbon - based molecule (incorrect). Option C lists elements, not products. Option D has oxygen (reactant). Option B has \( \text{CO}_2 \), \( \text{H}_2\text{O} \) (as vapor) and heat, which are correct products.

Answer:

B. Carbon dioxide, water vapor, and heat
