Which type of chemical reaction absorbs energy from its surroundings?

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

Answer: (A)

Verified step by step guidance

1. Understand the difference between endothermic and exothermic reactions: Endothermic reactions absorb energy (usually heat) from their surroundings, while exothermic reactions release energy to the surroundings.
2. Recall that neutralization and combustion reactions are typically exothermic, meaning they release energy.
3. Identify that an endothermic reaction requires energy input to proceed, which means it absorbs energy from the surroundings.
4. Recognize that the question asks for the type of reaction that absorbs energy, which matches the definition of an endothermic reaction.
5. Conclude that the correct answer is an endothermic reaction because it is the type of chemical reaction that absorbs energy from its surroundings.
