The following are clips of other people solving extended stoichiometry problems. You may solve the problem their way, my way, or your own way!!! I have listed the problem statements before the video. Try each problem before viewing the video and the answer. Good luck!!!
Problem #1:
Given the following reaction:
N2(g) + 3 H2(g) ==> 2 NH3(g)
If 11.2 L of N2 reacts, how many L of NH3 form?
(Note: it is not mentioned that this problem is at STP, but he solves the problem originally like it is at STP. He also shows you a method of solving the problem if it wasn't at STP.)
Video (problem starts at ~4:18 mark):
Problem #2:
Given the following reaction:
Zn + HCl ==> ZnCl2 + H2(g)
At STP, how many liters of H2 are formed by reacting 38.2 g of Zn?
Video:
(Note: His sig figs are incorrect in the problem. He should report his answer to 3 sig figs only.)
