One of the parameters monitored for in reactor water chemistry is boron. which of the following is a reason for boron addition? to control reactivity to protect pumps to inhibit corrosion to preclude caustic stress corrosion

To control reactivity.

Explanation:

One of the natural isotopes of boron (¹⁰B) with an abundance of 20%, has a high neutron cross section, wich means that it can absorb a high number of protons, thus helping in the leakage of protons to the outiside. Boron is usually added to the reactor water in form of boric acid (H₃BO₃).

idk

explanation:

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
