Answer Key: B Part 3 of 3 - 0.0/ 10.0 Points Question 11 of 12 0.0/ 5.0 Points Ammonia gas decomposes according to the equation: 2NH 3 (g) → N 2 (g) + 3H 2 (g) If 15.0 L of nitrogen is formed at STP, how many liters of hydrogen will be produced (also measured at STP)? STP=22.4L 15/22.4 = .669 mol NH3 : H2 = 2:3 NH3=.669 -> H2= .669/2 x 3 = H2=1.003 Answer = 1/2 Mol of H2 Feedback: Gas Laws are found in Chapter 11

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
