B) Heat is produced in the reaction and must be shown in the balanced equation.
C) Balancing the equation requires knowing whether the products are gases or liquids.
D) Oxygen is consumed in the reaction and must be shown in the balanced equation.

Question

Quizplus · Accepted Answer

In the complete combustion of a carbon compound, oxygen is consumed and must be shown in the balanced equation. The balanced equation for the combustion of a hydrocarbon is typically of the form: hydrocarbon + oxygen → carbon dioxide + water + heat. The carbon compound is also consumed in the reaction and should appear in the balanced equation. Heat is produced in the reaction, but it is not typically shown in the balanced equation. Knowing whether the products are gases or liquids is not necessary for balancing the equation.
