Abomb 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. in an experiment, a 1.1070 g sample of fumaric acid (c4h4o4) is burned completely in a bomb calorimeter. the calorimeter is surrounded by 1.093ă—103 g of water. during the combustion the temperature increases from 22.10 to 24.52 â°c. the heat capacity of water is 4.184 j g-1â°c-1. the heat capacity of the calorimeter was determined in a previous experiment to be 891.1 j/â°c. assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of fumaric acid based on these data. c4h4o4(s) + 3o2(g) 2 h2o(l) + 4 co2(g) + energy

A1.000 g sample of octane (c8h18) is burned in a bomb calorimeter containing 1200 grams of water at an initial temperature of 25.00ºc. after the reaction, the final temperature of the water is 33.20ºc. the heat capacity of the calorimeter (also known as the "calorimeter constant") is 837 j/ºc. the specific heat of water is 4.184 j/g ºc. calculate the heat of combustion of octane in kj/mol.

A1.800-g sample of solid phenol (c6h5oh(s)) was burned in a bomb calorimeter, which has a total heat capacity of 11.66 kj/∘c. the temperature of the calorimeter plus its contents increased from 21.36∘c to 26.37∘c. (a)-write a balanced chemical equation for the reaction that takes place in the bomb calorimeter. express you answer as a chemical equation including phases. water vapor, h2o(g), will initially form as part of this reaction. however, the temperature of all substances will eventually equilibrate in the bomb calorimeter (to 26.37∘c), which signifies that water and carbon dioxide, h2o(l) and co2(g), are the eventual products of a combustion reaction in a bomb calorimeter. (b)- what is the heat of combustion per gram of phenol?
