We are burning a candle underneath a calorimeter until the temperature of the water increases by 10 degrees. We are then asked to calculate the energy released per grams of paraffin. We are given the accepted energy content as well

the question is:

patrick thinks that burning the candle until the temperature has risen only 5 degrees will yield more accurate results but Caitlin thinks it won't make a difference. Who is right and why?

A student performed this experiment, using a cocktail peanut. Before it was burned, the peanut half weighed 0.353 g. After burning, the residue weighed 0.016 g. The energy released by the combustion increased the temperature of 200.0 ml of water in the calorimeter by 7.2Â° C.

1.) calculate the mass of peanut consumed in the combustion.

2.) Calculate the mass, in kilograms, of water heated.

3.) Calculate the total energy released by the combustion, using the water temperature increase, the water mass, and the specific heat capacity of water.

4.) Calculate the energy released per gram of peanut consumed in the combustion.

The combustion of 0.1584 grams of benzoic acid increases the temperature of a bomb calorimeter by 2.45 (degrees) C. Calculate the heat capacity of this calorimeter. (The energy released by combustion of benzoic acid is 26.42 kJ/g.) A .2130 g sample of vanillin C8H8O3 is then burned in the same calorimeter, and the temperature increases by 3.25 C. What is the energy of combustion per gram of vanillin? Per mole of vanillin?
