Evaluate (714 mm )/(37 s ) to three significant figures and express answer in si units using an appropriate prefix.

The SI base units for length is meter (m) and for time is seconds (s).

The given ratio is

Converting mm/s to m/s as:

Since, 1 mm/s = 0.001 m/s

So,

Since, zeroes to the left side of the non-zero number are not significant hence, the evaluation of to three significant figures and answer in SI units is .

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: )
