A 4.117 g impure sample of glucose (C6H12O6) was burned in a constant-volume calorimeter having a heat capacity of 19.65 kJ/C. If the rise in temperature is 3.134C, calculate the percent by mass of the glucose in the sample. Assume that the impurities are unaffected by the combustion process and that (change in U = change in H). Check any necessary thermodynamic data in the appendices of your textbook/online.

At constant volume, the heat of combustion of a particular compound, compound A, is −3294.0 kJ/mol. When 1.127 g of compound A (molar mass = 109.35 g/mol) is burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 7.283 °C. What is the heat capacity (calorimeter constant) of the calorimeter? Suppose a 3.157- g sample of a second compound, compound B, is combusted in the same calorimeter, and the temperature rises from 23.23 °C to...

The heat of combustion of octane is -5430 kJ/mol.
1.000 g sample of octane (C8H18) is burned
in a bomb calorimeter at an initial temperature of 25.00ºC.
The heat capacity of the calorimeter (also known as the
“calorimeter constant”) is 837 J/ºC.
Calculate
E for the combustion of octane. (You will need a balanced chemical
equation to find
H)
