What is the pH of a 0.7M NaOH solution

1. 13.85
2. -13.85
3. 0.15
4. -0.15

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

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!

if you need further assistance, let me know: )
