Chapter 5 and 6 Review Review Chapter 5 and 6 CHM1025 1. Nitric oxide (nitrogen monoxide) can be synthesized by burning ammonia in oxygen with a platinum catalyst (catalysts are not part of the products or reactants, i.e. they are not consumed in the chemical reaction). The products are nitric oxide and water. If 0.120 mol of ammonia and 0.140 mol of oxygen are reacted, which is the limiting reactant? How many grams of nitric oxide are obtained? 2. If 4.15 g of titanium(IV) oxide, 6.78 g chlorine, and 5.67 g of carbon are reacted and 8.45 g of titanium(IV) chloride are collected, what is the percent yield of the product? 3TiO 2 (s) + 4C(s) + 6Cl 2 (g) Æ 3TiCl 4 (g) + 2CO 2 (g) + 2CO(g) 3. Yellow tungsten(VI) oxide is reacted with hydrogen to yield tungsten metal and water. How many grams of tungsten can be synthesized from 4.81 kg of hydrogen and excess tungsten(VI) oxide? 4. In the Andrussov Oxidation process, hydrogen cyanide is synthesized by reacting gaseous ammonia, oxygen, and methane (CH 4 ) to give hydrogen cyanide and water.

    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.
