Active Learning Questions 117 5. Figure 3.5 illustrates a schematic diagram of a combustion device used to analyze organic compounds. Given that a certain amount of a compound containing car- bon, hydrogen, and oxygen is combusted in this device, explain how the data re- lating to the mass of CO 2 produced and the mass of HzO produced can be manip- ulated to determine the empirical formula. 6. What is the difference between the empirical and molecular formulas of a com- pound? Can they ever be the same? Explain. 7. Consider the hypothetical reaction between A z and AB pictured below. What is the balanced equation? If 2.50 mol A z is reacted with excess AB, what amount (moles) of product will form? If the mass of AB is 30.0 amu and the mass of A z is 40.0 amu, what is the mass of the product? If 15.0 g of AB is reacted, what mass of A z is required to react with all of the AB, and what mass of product is formed? 8. What is a limiting
