The percent by mass of bicarbonate (HCO3−) in a certain Alka-Seltzer product is 32.5 percent. Calculate the volume of CO2 generated (in mL) at 37°C and 1.00 atm if a person were to accidentally ingest a 3.41-g tablet without following instructions. (Hint: The reaction occurs between HCO3− and HCl acid in the stomach.)

I Need the pre-lab
Questions, please
An Alka-Seltzer tablet consists of NaHCOs (sodium bicarbonate), citric acid (H3C&HsO; citric acid is triprotic), aspirin and other inert ingredients. When dissolved in water, citric acid and NaHCO3 components react as follows: In the first part of the experiment, we will determine the mass of NaHCO in a tablet of Alka Seltzer. To do this, we will use a known mass of a powdered sample of Alka-Seltzer and determine the mass of CO2 gas...
6. Commercial drain cleaners sometimes contain a mixture of aluminum powder and NaOH. When the mix is poured down a clogged drain, the following occurs: 2NaAl(OH)4(aq) + 3H2(g) + Heat 2 NaOH(aq) + 2AI(s) + 6H2O() Heat melts grease and gas breaks up the clogs. What volume of hydrogen is formed at 1.00 atm and 21.0°C when 5.00 g of Al are treated with excess NaOH? 7. The mass percent of HCO3 in a certain 3.20 g Alka Seltzer tablet...
Below is a lab hand out for the questions. All my data for the questions are filled out below in BOLD LETTERING. All the questions I need answered are at the bottom with boxes where to put the answers. Background Alka-Seltzer� is an over-the-counter antacid and pain relief drug. The tablet contains aspirin (acetylsalicylic acid), citric acid, and sodium bicarbonate (NaHCO3). Sodium bicarbonate (NaHCO3) is responsible for the effervescent action of Alka-Seltzer. In this lab we will investigate the reaction...
