In a nuclear power plant control rods are used to a. speed up the reaction. b. slow down the reaction. c. feed material to the reaction. d. stabilize the walls of the nuclear reactor.

speed up the reaction.

slow down the reaction.

Explanation:

Control rods are used in nuclear reactors to control the fission rate of reactions. Their compositions includes certain elements such as boron, cadmium, silver, or indium, which are capable of absorbing many neutrons without themselves fissioning.

Control rods may be inserted into a nuclear reactor core to reduce the reaction rate or withdrawn to increase it depending on the desired rate of reaction.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
