Explain while 0.55 g of compound X is burned entirely in a bomb calorimeter containing 3000 grams of water, a temperature rise of 0.23 C is observed. Explain what is Urxn for the combustion of compound X? Define the hardware component of the calorimeter has a heat capacity of 3.69 kJ/C. The given heat of water is 4.184 J/g•C, and the MW of X is 56.0 g/mol.
