8. What two things can happen to energy in a chemical reaction?

It can either release energy or take in energy.

Explanation:

In an exothermic reaction, the energy is released from the reaction and is typically released through the energy of heat or light.

In an endothermic reaction, the energy is absorbed by the reaction and often results in the chemical reaction becoming cold.

Explanation:

All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy. The law of conservation of energy states that matter cannot be created or destroyed.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
