An endothermic reaction that occurs when an ionic compound dissolves in water to make an ionic solution

• Dissolution of ionic compounds in water is an endothermic reaction.

• Dissolution of ionic compounds in water releases heat.

• Ionic compounds do not dissolve in water.

• Dissolution of ionic compounds in water is an exothermic reaction.

List the two ways that energy is involved in chemical reactions.

• Chemical energy and nuclear energy

• Kinetic energy and potential energy

• Catalytic energy and thermal energy

• Activation energy and energy changes (exothermic and endothermic reactions)

The difference between fusion and fission. Why do certain elements undergo fusion or fission? 7. Which type of nuclear reaction is used in modern-day nuclear reactors? Why is the other type of nuclear reaction not used in modern-day energy product

• Fission is not used in modern reactors; only fusion is utilized.

• Fission is used in modern-day nuclear reactors; fusion is not used due to the extreme conditions required.

• Both fusion and fission are used equally in modern reactors.

• Fusion is easier to control than fission in energy production.
