References Use the References to access important values if needed for this question. A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Ignition wires Thermometer Stirrer heat sample In an experiment, a 0.5207 g sample of 1,6-hexanediol (C6H1402) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.087x108 g of water. During the combustion the temperature increases from 22.50...

Please help with all parts below:
Problem 15.76 The contribution of the combustion of various fuels to the buildup of CO2 in the atmosphere can be assessed in different ways. One way relates the mass of CO2 formed to the mass of fuel burned; another relates the mass of CO2 to the quantity of heat evolved in the combustion. The heat released per mole of each substance is C (graphite), 393.5 kJ C2Ho (g), 1554 kJ, and C4H10 (g), 2877...

Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment. Use enthalpy of formation data to calculate the number of moles of CO2(g) produced per megajoule of heat released from the combustion of each fuel under standard conditions (1 atm and 25 �C). Each must be in mol * MJ^-1 (a) coal, C(s, graphite) (b) natural gas, CH4(g); (c) propane, C3H8(g);...
