Show all work for f 1) Consider this constant pressure (coffee cup) calorimetry experiment that was performed in a laboratory: a. A 20.0g block of zinc (s-0.390J/g.°C) was heated to 100°C and then placed in 75.0mL of water (s-4.184J/g.°C) in the coffee cup, and the temperature of the water increased from 22.5°C to 24.6°C. Calculate the heat capacity of the coffee cup. b. 5.00g of solid NaOH was placed in 75.0mL of water at 23.8° C in the same coffee cup, and the temperature of the water increased to 39.7°C. Calculate the enthalpy of solution of sodium hydroxide. 2) Consider this constant volume (bomb) calorimetry experiment that was performed in a laboratory a. A constant volume (bomb) calorimeter was calibrated in an analytical laboratory by burning 1.057g of benzoic acid (C7H602) which has an enthalpy of combustion of -3228 kJ/mol. The temperature of the calorimeter rose from 22.75°C to 29.00°C. What is the heat capacity of the calorimeter? b. Nitromethane (CH3NO2) is a liquid fuel that is used in top fuel drag racing and model airplane engines. A 0.57g sample of nitromethane was placed in the constant volume (bomb) calorimeter. The temperature of the calorimeter rose from 23.25°C to 24.73°O. What is the enthalpy of combustion of nitromethane?

Bomb calorimetry is a technique used to determine the enthalpy of combustion, usually in O2, of a chemical species. A known amount of compound is placed inside a fixed volume container that is, in turn, filled with oxygen at a high enough pressure to ensure complete combustion. The fixed-volume container (the 'bomb') is then inserted into a bucket containing a precisely known volume of water. The oxygen and compound are ignited, and the temperature change in the water is recorded....

Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters. A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer; energy changes in a reaction are observed via a temperature change of the solution in the cup. Bomb calorimeters are used to measure combustion and other gas-producing reactions, where the reaction is observed in a strong, sealed vessel....

A bomb 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 0.3320 g sample of naphthalene (C10Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.092x103 g of water. During the combustion the temperature increases from 22.54 to 25.04 °C. The heat capacity of water is 4.184 Jg=1°C-1 The heat capacity of the calorimeter was determined...
