I need help with these questions in chemistry lab

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

)
