If the heat capacity of the calorimeter and its contents is , calculate the heat released by this combustion, , to 2 significant figures.
From the value of , calculate the molar enthalpy of combustion for fructose to 2 significant figures.
The addition of 3.15 g of to a solution of 1.52 g of in 100 g of water in a calorimeter caused the temperature to fall by . Assuming the specific heat of the solution and products is , what is the approximate amount of heat absorbed by the reaction? Give your answer in kilojoules to two significant figures.
The reaction can be represented by the following equation.
When a 3.00 g sample of was added to g of water in a coffee cup calorimeter, the temperature decreased by . How much heat is involved in the dissolution of the ? Assume that the specific heat of the solution is .
