What is the purpose of filling the calorimeter with oxygen? Explain. (maximum of 2 sentences).Consider the combustion of compressed methane, and liquid hydrogen. Which one will release more energy: 100 g of compressed methane or 100 g of liquid hydrogen? Explain how you came up with your answer. (max of 4 sentences)During the experiment, when calculating for ΔH using the formula ΔH = C x ΔT, can we calculate the ΔH without measuring the amount of water that we put inside the calorimeter? Explain why or why not. (max of 5 sentences)You accidentally forgot to measure the mass of the octane that you transferred in the crucible. You already started the calorimeter and it is too late to stop the equipment. Is it still possible to calculate the energy (in Joules) of octane? Explain. (max of 2 sentences)
