A chemist carefully measures the amount of heat needed to raise the temperature of a sample of from to . The experiment shows that of heat are needed. What can the chemist report for the molar heat capacity of

Agas mixture with a total pressure of 745 mmhg contains each of the following gases at the indicated partial pressures: co2, 245 mmhg ; ar, 119 mmhg ; and o2, 163 mmhg . the mixture also contains helium gas. part a what is the partial pressure of the helium gas? phe p h e = nothing mmhg request answer part b what mass of helium gas is present in a 10.2-l sample of this mixture at 283 k ? m m = nothing g request answer

What reaction is taking place? 02 + c3h8 = h20 + co2
