A sample of cold water was mixed with a sample of hot water inside a calorimeter, and the final temperature of the cold water was 40 °C. Which statement is true about the hot water in the calorimeter? It absorbed 40 joules. It absorbed 80 joules. Its final temperature was 80 °C. or Its final temperature was 40 °C.
heat sample A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. Water In the laboratory a student burns a 0.449-g sample of 1,6-hexanediol (C,H1402) in a bomb calorimeter containing 1080. g of water. The temperature increases from 25.50 °C to 28.20 °C.

Hess's law states that "the heat released or absorbed in a chemical process is the same whether the process takes place in one or in several steps." It is important to recall the following rules: Part A 1. When two reactions are added, their enthalpy values are added. Calculate the enthalpy of the reaction 2. When a reaction is reversed, the sign of its enthalpy value changes. 3. When the coefficients of a reaction are multiplied by a factor, the enthalpy value is multiplied by that same factor. 2NO(g) + 02 (g)–→2NO2(g) given the following reactions and enthalpies of formation: 1.
