1) If you had not dried the solid, would the calculated percent yield have been higher, lower, or unchanged? Explain

2)Boron trichloride is prepared from the following reaction. 2B₂O₃ + 6Cl₂ + 3C --> 4BCl₃ + 3CO₂ If 3.456g of B₂O₃ is mixed with 9.9216g of Cl₂ and 2.459g of C then answer the following questions.

2a) What is the theoretical yield of boron trichloride in grams?

2b) How much of each of the excess reagents would remain once the reaction is complete? (report in grams)

3) If the yield of the reaction in question 2 is known to be only 67.89% using stoichiometric amounts, how much (g) of each of the three reagents would you need to obtain 10.000g of boron trichloride?
