Question

question 1
what type of reaction releases energy?
endothermic
exothermic
question 2
what type of reaction absorbs energy?
endothermic
exothermic
question 3
energy is select when bonds are formed.

Explanation:

• For Question 1: Exothermic reactions release energy. This is a fundamental concept in chemistry where the products have lower energy than the reactants, and the excess energy is given off (usually as heat).
• For Question 2: Endothermic reactions absorb energy. Here, the reactants absorb energy (often in the form of heat) to form products with higher energy.
• For Question 3: Energy is released when bonds are formed. Bond - formation is an exothermic process. When atoms come together to form a bond, they reach a more stable (lower - energy) state, and the excess energy is released.

Answer:

Question 1: B. Exothermic
Question 2: A. Endothermic
Question 3: Released
