1. Assume that your vinegar contained a small amount of citric acid (a triprotic acid). Using the same experimental data, would vou expect the molarity of this sample to be POST-LAB QUESTIONS the same as or different than a sample which contained only pure acetic acid? 2 Assume that the tip of your buret was not properly filled with NaOH solution. It contained an air bubble which was eliminated during the titration. Would the caleulated molarity of the vinegar be...

2. Carly the chemistry student performs an experiment with vinegar (active ingredient acetic acid, CH,COOH) and baking soda (NaHCO3). Her professor asks her to place varying amounts of baking soda and vinegar into sealable plastic bags, quickly seal the bags, and observe the reaction. The balanced chemical equation for the reaction is given here NaHCO3(aq) + CH.COOH(aq) → CO2(g) + H20(1) - NaCH,COO(aq) a) Use limiting reagent calculations to fill in the following table.

(1 point) Two chemicals A and B are combined to form a chemical C. The rate of the reaction is proportional to the product of the instantaneous amounts of A and B not converted to chemical C. Initially there are 63 grams of A and 100 grams of B, and for each gram of B, 2 grams of A is used. It has been observed that 40.75 grams of C is formed in 10 minutes. How much is formed in...
