Rank the four gases (air, exhaled air, gas produced from the decomposition of H2O2, gas from decomposition of NaHCO3) in order of decreasing concentration of CO2.

I need to know how to physically find the percentages of CO2 in H2O2 & NaHCO3
Astronomers use chemical signatures to determine the age and .... Gas mixtures that contain more than 4% hydrogen in air are potentially explosive. ... water vapor, carbon dioxide, and several other gases
