Question

A student used a bomb calorimeter to determine the heat of combustion of an unknown compound. If the student ignored the heat capacity of the bomb calorimeter, the heat capacity of the unknown compound would be _________ the accepted value.

a. greater than (i.e., less negative)
b. less than (i.e., more negative)
c. equal to

Answer 1

A student using a bomb calorimeter to determine the heat of combustion of an unknown compound. If the student ignored the heat capacity of the bomb calorimeter, the heat capacity of the unknown compound would be greater the accepted value.

Step-by-step explanation:

• A calorimeter is an instrument used to estimate the heat.
• The bomb calorimeter essentially contains ignition tube, stirrer, bomb, water, sample, dewar flask, and thermometer.
• Calorimetry works on the principle that if there is no heat loss in enclosing the hot body's total heat loss is equal to the total heat obtained by a cold body.
• If the student ignored the heat capacity of the bomb calorimeter, the heat capacity of the unknown compound would be greater the accepted value.
