7. Draw a flowchart or other graphic organizer to show how you would determine the mass of oxygen, O2(g), that would be produced by the decomposition of 5.78 g of hydrogen peroxide, H,02(2), as shown in the following chemical equation: 2H02(1) 2H20() + O2(g) ANSWER: 8. Acetylene, CH2(g), is a gas used in welding. If 2.34 x 10g of calcium carbide, Cacz(s), reacts completely with water, what mass of acetylene will be produced? CaCz(s) + 2H20(1) - Ca(OH)2(aq) + C2H2(g) ANSWER: 9. The fertilizer ammonium nitrate, NH, NO3(s), produces dinitrogen monoxide, N2O(g), and water vapour when it decomposes. What mass of water vapour is produced when 3.67 g of ammonium nitrate decomposes? NH_NO3(s) - N2O(g) + 2H2O(g)
