1. 4-bromo-6-methylheptanal 2. 3-methylheptan-3-ol
3.Acetophenone
4. 2-methylpropyl ethanoate

the product of the pressure and volume is also constant

the correct answer is:

a. formation of precipitation

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!
