INTERACTIVE EXAMPLE The Average Mass of an Element = When a sample of natural silver is vaporized and injected into a mass spectrometer, the results are shown in the figure here. Ag-107 is present in 51.84% abundance. Ag-109 is present in 48.16% abundance. The masses of these two isotopes are Ag-107 = 106.91 u and Ag-109 108.90 u.

QUESTION#1: TOPIC: Limiting reactants Gaseous butane (CH3CH22CH3) will react with gaseous oxygen (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O). Suppose 1.16 g of butane is mixed with 6.4 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Round your answer to 3 significant digits. ? g QUESTION #2: TOPIC: Solving for a reactant in solution Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCl), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved (NaHCO3) neutralizes excess (HCl) through this reaction: HCl(aq)+NaHCO3(aq) →NaCl(aq) +H2O(l) +CO2(g) The (CO2) gas produced is what makes you burp after drinking the solution. Suppose the fluid in the…
