An Olympic swimming pool is 50 meters long. You swim from one end to the other four times. How many meters do you swim?

200 meters

Explanation:

if u swim for each end 4 times, and its 50 meters long, 50 x 4 = 200 meters

i don,t know so just answer mine

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: )
