Our balanced chemical reaction is 8 moles of phosphorus, p4, is reacting with 3 moles of sulfur, s8, in order to produce 8 moles of p4, s3.
00:19
So, which of the following statements is incorrect? the first statement says 4 moles of p4 reacts with 1 .5 moles of s8.
00:30
So, 4 moles of p4 is going to be half of the coefficient, so it needs to react with half of this 1 .5 moles in order to make half of this 4 moles of p4, s3.
00:46
So that first one is true.
00:48
Then, the second statement says sulfur is the limiting reactant when we have 4 moles of p4, which is half of the 8 coefficient, and 4 moles of s8.
01:05
If we have 4 moles of p4, then in order to have all, have enough sulfur, we're gonna need just half of that, 1 .5 moles.
01:20
But because we have 4 moles of sulfur, then we have an excess amount of sulfur, and phosphorus is the limiting reactant.
01:32
So that statement is false, and to make it true, it should state that p4 is the limiting reactant, and everything else is, would be correct...
