Which of the following statements is true?

a. chemical reaction rates vary with the conditions of the reactions, but nuclear decays rates do not.

b. nuclear decay rates vary with the conditions of the reaction, but chemical reaction rates do not.

c. both chemical reaction and nuclear decay rates vary with the conditions of the reaction.

d. neither chemical reaction rates nor nuclear decay rates vary with the conditions of the reaction.

A

Chemical reaction rates vary with the conditions of the reaction, but nuclear decay rates are constant.

Explanation:

B/c chem reactions can be affected by temperature, pressure, etc. whereas, nuclear decays are constant. The decay rate itself is measured over a long period of time and it remains constant I believe.

there all right good

explanation:

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
