The speed of a chemical reaction

a. is constant no matter what the temperature is.

b. is independent of the amount of contact surface of a solid involved.

c. between gases should in all cases be extremely rapid because the average kinetic energy of the

molecules is great.

d. between ions in aqueous solution is extremely rapid because there are no bonds that need to be

broken.

option C. between gases should in all cases be extremely rapid because the average kinetic energy of the molecules is great.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
