6. You have $50.00. You buy a CD for $15.50. You sell it to your friend for $12.00. He doesn't like it, so you buy it back for $10.00. There is a scratch on it, so you return it to the store and get
your money back. How much did you lose or make?

the answer is that you made $2

Explanation:

Explanation:

Theoretical yield is the amount supposedly produced by the reaction if it was complete. The balanced chemical reaction is:

C2H6 + Cl2 = C2H5Cl + HCl

We use the amounts given for the reactants as the starting point of the calculations to determine the limiting reactant. We do as follows:

150 g C2H6 ( 1 mol / 30.08 g ) = 4.987 mol

205 g Cl2 ( 1 mol / 70.9 g ) = 2.891 mol

Therefore, the limiting reactant would be Cl2 since it would be consumed completely first in the reaction. We use this for the theoretical yield.

2.891 mol Cl2 ( 1 mol C2H5Cl / 1 mol Cl2 ) = 2.891 mol C2H5Cl (THEORETICAL YIELD)

172 g ( 1 mol / 64.52 g ) = 2.666 mol C2H5Cl ( ACTUAL YIELD)

Percent yield = 2.666 / 2.891 x 100 = 92.21%
