Which type of chemical reaction results in the absorption of energy?

• A. Endothermic reaction
• B. Combustion reaction
• C. Neutralization reaction
• D. Exothermic reaction

Answer: (A)

Verified step by step guidance

1. Understand the difference between endothermic and exothermic reactions: Endothermic reactions absorb energy from the surroundings, while exothermic reactions release energy.
2. Recall that combustion reactions are a type of exothermic reaction because they release energy in the form of heat and light.
3. Recognize that neutralization reactions, which involve an acid and a base, typically release energy, making them exothermic as well.
4. Identify that an endothermic reaction is characterized by the absorption of energy, often in the form of heat, causing the surroundings to feel cooler.
5. Conclude that the type of chemical reaction that results in the absorption of energy is an endothermic reaction.
