1 - Many home barbeques are fueled with propane gas (C3H8). What mass of carbon dioxide (in kg) is produced upon the complete combustion of a typical tank of propane containi 18.9 L. The density of the propane is 0.621 g/ mL Hint: begin by writing a balanced rquation for the combustion reaction.
2- When SiO2 is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. in an industrial preparation of silicon, 155.8 Kg of SiO2 reacts with 78.3 Kg of carbon to produce 66.1 Kg of silicon. Determine the limiting reactant yield, and percent yield for the reaction.
