a 5.00 g sample of TNT (C7H5N2O6) is burned in a bomb
calorimeter with a heat capacity of 420 J/degreeC. The calorimeter
contained 610 grams od water (4.18J/gdegreeC) and the temperature
of the water was measured to go from 20.0 degree C to 22.5 degree
C. What is the heat of combustion of TNT?.
I know the answer, but can you give me a step by step
explanation of how to get it?

Ammonium nitrate (NH4NO3(s) decomposes into nitrogen, oxygen and
water. If 10 g of ammonium nitrate decompose entirely at 350 *C
with ΔrxnHo = -289. kJ
- How much heat is liberated?
- How much work would be done by the system?
- What will be the pressure of the system if, after completion
of the reaction, the volume is 1.0 L and the temperature is
120°C?

A 1.800 g sample of octane, C8H18, was burned in a bomb
calorimeter whose total heat capacity is 11.66 kJ/°C. The
temperature of the calorimeter plus contents increased from 21.59°C
to 29.44°C. What is the heat of combustion per gram of octane? What
is the heat of combustion per mole of octane? In a bomb calorimeter
(where pressure is NOT constant) what is the heat of reaction equal
to?

A. When a 0.235-g sample of benzoic acid is combusted in a bomb
calorimeter, the temperature rises 1.644 ∘C . When a 0.275-g sample
of caffeine, C8H10O2N4, is burned, the temperature rises 1.585 ∘C .
Using the value 26.38 kJ/g for the heat of combustion of benzoic
acid, calculate the heat of combustion per mole of caffeine at
constant volume.
B. Assuming that there is an uncertainty of 0.002 ∘C in each
temperature reading and that the masses of samples...

kJ/g) of the hydrogen. Report your answer to three significant
figures.

A bomb calorimeter, or constant volume calorimeter, is a device
often used to determine the heat of combustion of fuels and the
energy content of foods. Since the "bomb" itself can absorb energy,
a separate experiment is needed to determine the heat capacity of
the calorimeter. This is known as calibrating the calorimeter. In
the laboratory a student burns a 0.466-g sample of 1,8-octanediol
(C8H18O2) in a bomb calorimeter containing 1200. g of water. The
temperature increases from 25.90 °C...
