Only 100 L of N2 are required to react with 300 L of H2. There would be 150 L of N2 remaining after the reaction. b) what volume of gaseous ammonia will be produced? 3 marks 1 mole of N2 3 moles of H2 creates 2 moles of NH3 100 L of N2 reacts with 300 L of H2 to create 200 L of NH3. 3. Gaseous bromine is produced by the reaction indicated below. If the reactants and the products are in a gaseous state at the same temperature and pres- sure, what will be the volume of bromine produced during a reaction of 3.50 L of hydrogen bromide with 2.00 L of oxygen? 3 marks Hint: Find which reactant is in excess. 4HBr + O 2 = 2Br 2 + 2H 2 O 4 moles HBr 1 mole O2 creates 2 moles Br2 2 moles H2O 4 moles of HBr is 3.50 L 1 mole of O2 would be 0.875 L (an excess of 1.125 L of O2). In this reaction there would be 1.75 L of Bromine produced. Submission Instructions Submit your assignment using the drop box on the Assignment page for this unit. 2

### 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.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• 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.
