9. (05.06 MC) During an experiment, the percent yield of calcium chloride from a reaction was 80.34%. Theoretically, the expected amount should have been 115 grams. What was the actual yield
from this reaction?
Caco, + HC - CaCl + Co, + H20 (5 points)
A. 090.1 grams
B. 92.4 grams
C. 109.2 grams
D. 115.3 grams

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: )

um i think it might be a car?

the awnser is group 12

they all get energy from eating other animals, dead animals to be more precise.
