1) A lab theoretically should produce 2.3g of precipitated calcium carbonate. A group of students runs the lab and collects 2.1g. What is the percent yield that this lab group obtained? 2) How many grams of Ag,S will theoretically be produced when 3.94 g of AgNO; and an excess of Na,S are reacted together? Na,S(aq) + 2 AgNO;(aq) → Ag,S(s) + 2 NaNO3(aq) 3) 15.3 grams of Lithium is dropped into a solution containing excess copper II phosphate. When the reaction is completed, 62.5 grams of copper is collected in the lab. What is the percent yield? 6 Li (s) + 1 Cu3(PO4)2 (aq) à 2 L¡3PO4 (aq) + 3 Cu (s) 4) 2.3 grams of Aluminum is placed into a solution containing excess copper II chloride. When the reaction is completed, 6.25 grams of copper is collected in the lab. What is the percent yield? + 3 CuCl2 (aq) 2 Al à 2 AIC13 (aq) + 3 Cu (s) (s)

4. Gasoline can be reasonably approximated as C9H20 with a density of 0.718 g/mL. Diesel can be reasonable approximated as C14H30 with a density of 0.763 g/mL. (Both gasoline and diesel are complicated mixtures. These formulas are something like weighted averages of the formulas of the different components, where the weighting is based on various quantifiable behaviors. That is, using these artificial formulas for gasoline and diesel allows one to calculate average properties that match what petroleum engineers might measure.) The enthalpy change from burning one mole of gasoline is -6160 kJ. The enthalpy change from burning one mole of diesel is -7940 kJ. Determine which fuel generates the biggest enthalpy change per gram burned, and which generates the biggest enthalpy change per mL burned.
