Calculate the ratio of h+ ions to oh-ions at a ph = 6.
find the concentration of h+ ions to oh-ions listed in
table b of your student guide. then divide the h+
concentration by the oh-concentration. record this
calculated ratio in table a of your student guide.
compare your approximated and calculated ratios of h+
ions to oh-ions at a ph = 6. are they the same? why or
why not? record your explanation in table a.
what is the concentration of h+ ions at a ph = 6?
mol/l
what is the concentration of oh-ions at a ph = 6?
mol/l
what is the ratio of h+ ions to oh-ions at a ph = 6?

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!

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

the answer is d.) potassium
