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...

4.2 Behavior of Gases Students will perform a simple reaction between NaHCO,+CH,COOH, or commonly known as baking soda and vinegar. In the pre-lab, students determine the moles of CO, by using the ideal gas law, PV=ORT where: P= Pressure (atm) V=Volume (lters...) n = moles (mol) T = Temperature (kelvin) R-Gas constant (atm:Imol:K) Students used STP, standard temperature and pressure, to determine their temperatures and pressure for this experiment. At STP, T = 273 K, and P 1 atm. Solve...
