A compound is burned in a bomb calorimeter that contains 3.00 kg of water. If the combustion of 0.370 moles of the compound causes the temperature of water to raise 38.0 C, what is the molar heat of combustion of the compound? The specific heat of capacity of water is 4.184 J/g C. The answer needs to be in kJ/mol and have O decimal places.

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Thermometer Stirring rod A student heats 66.89 grams of platinum to 99.25 °C and then drops it into a cup containing 83.90 grams of water at 22.41 °C. She measures the final temperature to be 24.37.°C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.72 J/°C.

Acetylene, C,H,, is used in welding torches. It releases a lot of energy when burned in oxygen. The combustion of one gram of acetylene releases 48.2 kJ. A 0.750-gram sample of acetylene is burned in a bomb calorimeter (heat capacity = 1.117kJ/°C) that contains 800.0 g of water. The final temperature of the bomb and water after combustion is 35.2°C. What is the initial temperature of the bomb and water?

4. 30.0 g of a substance (molar mass: 46 g/mo) required 262 J of heat to raise its temperature from 32.0°C to 37.4°C. What is the specific heat per gram and per mole of this substance?
A student conducted several calorimetry investigations. In the first of the investigations, the student heats a 21.0 g price of metal that is know to have a specific heat capacity of 0.449 J/g°C to a temperature of 80°C. Then a piece of metal is added to the beaker of water (70.0 grams at 20.00°C). The specific heat capacity of water is 4.187 J/g°C. If the student repeated the investigation with 50.0 g of water instead what would be different.
