Answer:
23
Explanation:
if if you look at the screenshot it has the explanation
I think b would make the most sense.
The correct match are as follows:
Boyles Law is about a gas at constant temperature. Therefore, the correct match would be the volume of a gas varies inversely with pressure if the temperature is kept constant.
Charles Law would be that the volume of a gas varies directly with temperature if the pressure is kept constant.
Gay-lussac's law would be that the pressure of a gas varies directly with temperature if the volume is kept constant.
(57.0 g B2O3 / (69.6202 g B2O3/mol) x (4mol BCI3 / 2 mol B2O3) = 1.64 mol BC13
(44.7 g C12) / (70.9064 g C12/mol) x (4mol BCI3 / 6mol C12) = 0.42027 mol BC13
(68.8 g C) / (12.01078 G C/mol) x (4mol BCI3 / 3 mol C) = 7.63 mol BCI3
C12 is the limiting reactant.
(0.42027 mol BCI3) X (117 . 170 g BCI3/mol) = 49.2 g BCI3 in theory.
