44. What mass (g) of carbon dioxide will be produced by the complete combustion of 0.4560 g of C 5 H 19 O? a. 1.054 b. 0.02395 c. 0.004790 d. 2.108 e. 0.5270 45. Why is carbon dioxide called a greenhouse gas? 46. What mass (g) of hydrogen is produced by the reaction of 4.73 g of magnesium with 1.83 g of water? Be sure to balance the reaction. Mg + H 2 O --> Mg(OH) 2 + H 2 47. Silver nitrate and aluminum chloride react with each other by exchanging anions: AgNO 3 + AlCl 3 --> Al(NO 3 ) 3 + AgCl What mass (g) of AgCl is produced when 4.22 g of AgNo 3 react with 7.73 g of AlCl 3 . The reaction must be balanced. 48. If the reaction of 3.82 g of magnesium nitride with 7.73 g of water produced 3.60 g of magnesium oxide, what is the percent yield of this reaction? Balance the reaction. Mg 3 N 2 + H 2 O NH 3 + MgO a. 94.5 b. 78.8 c. 46.6 d. 49.4 e. 99.9

49. What is the maximum mass (g) of Cu that is produced by the reaction of 30.0 g of CuO and 20.0 g of CH 4 ? 4CuO + CH 4 --> 2H 2 O + 4Cu + CO 2 50. The combination of 75.00 g of Ca(OH) 2 and 150.00 g of Na 3 PO 4 produces 75.00 g Ca 3 (PO 4 ) 2 via the equation below. What is the percent yield? 3Ca(OH) 2 (aq) + 2Na 3 PO 4 (aq) --> Ca 3 (PO 4 ) 2 (aq) + 6NaOH(aq)

### 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.
