Fernando is doing his pre-lab homework for Chemistry. He is asked to predict how many grams of CO, are produced if 2.09 mol of HCl are reacted according to this balanced chemical equation shown. CaCO3 +2 HCI → CaCl2 + CO2 + H20 He performs the following calculation. 1molEo, 2 metHCT 2.09 motHCI x 44.01 g CO. = 46.0 g CO, 1molEo, of the balanced On the day of the lab his group obtains 31.21 grams of CO2 as their experimental result. What is their percent yield in standard notation?

Ethanol (CH3CH2OH) is a clear, colorless liquid with a distinct odor and is the alcohol found in alcoholic beverages. In addition to its other physical properties (Table 1), alcohol is flammable and volatile, lending it to be used as a solvent, an antiseptic, a fuel, in thermometers, and in other laboratory procedures. As a psychoactive substance, it is one of the most widely consumed recreational drugs by humans. It suppresses certain functions of the brain while causing the classic symptoms of intoxication including slurred speech, unsteady walk, and disturbed sensory perceptions. Melting point Boiling point Density Molar mass -114.1°C 78.5°C 0.79 g/mL 46.07 g mol-1 Table 1: Physical properties of ethanol at 20°C Ethanol is produced by the fermentation of sugar. This process is catalyzed by zymase, an enzyme in yeast which changes simple sugars into ethanol and carbon dioxide. This fermentation reaction is represented by the equation in Figure 1.
