Chapter 5: Q30E (page 227)

When 1.0g of fructose, C6H12O6(s), a sugar commonly found in fruits, is burned in oxygen in a bomb calorimeter, the temperature of the calorimeter increases by 1.58藲C. If the heat capacity of the contents is 9.90kJ/藲C, what is q for this combustion?

Short Answer

Expert verified

The heat of combustion for this reaction is 15.6 kJ.

Step by step solution

01

Given data

Data we are provided with:

The mass of the fructose = 1.0 g

The increase in the temperature (鈭員) = +1.58藲C

The heat capacity of the calorimeter(C) = 9.90 kJ/藲C

02

Heat of combustion

The formula that is used in finding the heat of the combustion (q) in a bomb calorimeter is

C 脳 鈭員.

The heat of the combustion = 9.90 KJ/藲C 脳 1.58藲C

= 1.56 kJ
