2) Calculations to determine the amount of CO2(g) produced in the Baking Soda-Vinegar reaction Starting Material: 40 ml Vinegar - SpecificGrav (CH3COOH) = 1.05 & vol%(CH3COOH) = 5 vol% a) Calculate the stoichiometric amount (moles and grams) of sodium bicarbonate needed. [CH3COOH(aq.) + H2O(l)]+ NaHCO3(s) --> H2O(l) +CO2(g) + NaCH3COO(aq.) c) Given that 1 mol of an ideal gas at standard temperature and pressure occupies 22.4 L, calculate the Ideal Gas Constant (R) in units of liter-atm/mol-K. NOTE: Remember R is...

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 (HCI), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO, neutralizes excess HCl through this reaction: HCl(aq) NaHCO3(aq) NaCl(aq)+ H,O)+ Co,(0) 4 The CO, gas produced is what makes you burp after drinking the solution. Suppose...

Activity 10 How Much Product Will My Reaction Yield? 37 6. Carly the chemistry student performs an experiment with vinegar (active ingredient acetic acid, CH, COOH) and baking soda (NaHCO). Her professor asks her to place varying amounts of baking soda and vinegar into scalable plastic sandwich bags, quickly seal the bags, and observe the reaction. The balanced chemical equation for the reaction is given here. NaHCO, (aq) + CH,COOH(ag) - CO,(8) + H,O(l) + NaCH COO(ag) a) Use limiting...
