Question

______________ is an exothermic chemical reaction between a fuel and an oxidizer resulting in the generation of a substantive heat and often light.

A) Conduction
B) Convection
C) Combustion
D) Radiation

Answer 1

Combustion is an exothermic chemical reaction between a fuel and an oxidizer resulting in the generation of a substantive heat and often light. It involves the reaction of a substance with oxygen gas, releasing energy in the form of light and heat.

Step-by-step explanation:

Combustion is an exothermic chemical reaction between a fuel and an oxidizer resulting in the generation of a substantive heat and often light. It involves the reaction of a substance with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O₂ as one reactant. For example, the combustion of hydrogen gas produces water vapor: 2H₂ (g) + O₂ (g) → 2H₂O(g). Combustion reactions are also considered as exothermic reactions that release energy (as heat).
