The reaction between an antacid and a hydrochloric acid is given. Sodium hydrogen carbonate + hydrochloric acid gives salt (NaCl), water, and CO2 (gas). What's the volume of CO2 generated from 7.5 grams of sodium hydrogen carbonate and excess hydrochloric acid at standard temperature and pressure? Note: Plug moles of what's generated into ideal gas equation. Don't forgot to change temp into Kelvins.
