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 to 28.70 °C. The heat capacity of water is 4.184 J g-1°C-1. The molar heat of combustion is −5094 kJ per mole of 1,8-octanediol. C8H18O2(s) + 23/2 O2(g) 8 CO2(g) + 9 H2O(l) + Energy Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = ____J/°C

1.A bomb calorimeter, or a constant volume calorimeter, is a
device often used to determine the heat of combustion of fuels and
the energy content of foods. In an experiment, a 0.3807 g sample of
1,6-hexanediol (C6H14O2) is burned completely in a bomb
calorimeter. The calorimeter is surrounded by 1.139×103 g of water.
During the combustion the temperature increases from 25.30 to 27.59

Question 1
A calorimeter is a device which can be used to determine the
heat of reaction. The process of measuring the heat is known as
calorimetry. Based on the above statement and from your further
findings, answer the following questions:
a) Analyze the operational principle of a calorimeter in a
proper sequence. Organize your answer in the form of a flow diagram
:
b) Outline how does the operational principle of the calorimeter
is related to the First Law...

In an adiabatic, constant-volume bomb calorimeter, a combustion
of 0.7362g of naphthalene (C10H8) caused the temperature to rise of
5.707 Celcius. The final temperature was 298.000K. The heat
capacity of the calorimeter, Ccal was 10290 J/K . (Note: this value
of Ccal includes the contribution from water.) The molar enthalpies
of formation of CO2(g) and H2O(l) are: -393.522 kJ/mol, -285.830
kJ/mol, respectively Mm(C)= 12.01 g/mol and Mm(H)= 1.001 g/mol.

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. A student heats65.62grams ofzincto98.24 °C and then drops
it into a cup containing75.87grams of water at23.87 °C. She
measures the final temperature to be29.24 °C. The heat capacity of
the calorimeter (sometimes referred to as thecalorimeter constant)
was determined in a separate experiment to be1.54J/°C. Assuming
that no heat...
