There are five identical balloons, each filled to the same volume at 25 degrees Celsius and 1.0 atm pressure with pure gas indicated (there’s a drawing of five balloons labeled CO2, O2, He, N2, and CH4). CH4 and O2 are reacted. What is the minimum number of balloons of each of those gases would you need for a complete reaction, with no excess gas remaining?
I am assuring since the reaction would be CH4+2O2–>CO2+2H2O, you would need 2 balloons of O2 gas and one balloon of CH4 gas?
