(05.06 MC) During an experiment, the percent yield of calcium chloride from a reaction was 85.22%. Theoretically, the

expected amount should have

grams What was the actual yield from this reaction? (5 points)

CaCO3 + HCI - CaCl2 + CO2 + H20

been 113

96.3 grams

О 99.0 grams

113 grams

0 121 grams

96.3g is the actual yield from this reaction

Explanation:

Have been 113g...

The percent yield of a reaction is defined as one hundred times the ratio between actual yield (Our incognite) and the theoretical yielf (113g). The equation is:

Percent yield = 85.22% = Actual Yield / 113g * 100

0.8522 = Actual Yield / 113g

0.8522*113g =

96.3g is the actual yield from this reaction

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: )
