Imagine that a space mission is using ethane for a fuel. How much oxygen will the crew be required to bring along if the energy requirements for the mission are 1,000,000 kJ. Use the thermochemical equation that you created in question 1. (Equation from question 1 = -1420 KJ/mol)
The changes in the chromatograph resulting from changes in mobile phase composition (not all observed change are easily explainable-just explain what u can, in particular the general change to longer or shorter elusion times for all analyses
