In the opening scene of the movie Raiders of the Lost Ark, Indiana Jones tries to remove a gold idol from a booby-trapped pedestal. He replaces a gold (D = 19.32 g/cm²³) idol of dimensions 5.0 inches by 5.0 inches by 5.0 inches with a bag of sand of approximately double the volume with sand (D = 3.65 g/cm³). Is the bag of sand really equal to the gold idol or will Dr. Jones set off the trap? Explain your answer and include a mathematical explanation. ML Cm3

Chalcopyrite is among the most common varieties of copper ore. Assuming chalcopyrite is 34.4% copper by mass (34.4 grams copper per 100. grams of ore), how many kilograms of chalcopyrite would be needed to smelt 30.0 kilograms of pure copper?
In 1986 an electrical power plant in Taylorsville,Georgia, burned 8,376,726 tons of coal, a national record at the time.
SO2 is a product of coal combustion. It may combine with O2 and H2O in the atmosphere to form sulfuric acid, a component of acid rain. One way to reduce the formation of acid rain involves trapping the SO2 by passing smokestack gases through a spray of calcium oxide and O2. The product of this reaction is calcium sulfate. a) Write a balanced chemical equation describing this reaction by writing the product and adding coefficients. __SO2+__CaO+__O2=__CaSO4 b) How many metric tons of calcium sulfate would be produced from each metric ton of SO2 that is trapped?
