A 2.47 g sample of caffeine
(C8H10N4O2) burns in a
constant-volume calorimeter that has a heat capacity of 7.86 kJ/K.
The temperature increases from 297.65 K to 305.65 K. Determine the
heat (qv) associated with this reaction.
Now use the data above to find ΔE for the combustion of one mole
of caffeine.

A 1.34 g sample of caffeine (C8H10N4O2) burns in a constant-volume calorimeter that has a heat capacity of 7.71 kJ/K. The temperature increases from 297.65 K to 302.07 K. Determine the heat (qv) associated with this reaction. 1476 kJ/mol Now use the data above to find ΔE for the combustion of one mole of caffeine.

Ignition Wires Insulating Container in Sample Steel Bomb A 0.29 g sample of ethanol (Mw 33.0 g/mol) is burned in a bomb calorimeter that has a heat capacity of 4.31 k/oc. The temperature of the calorimeter increases by 2.79°C. Calculate the molar heat of combustion of ethanol using the data from experiment. Since this experiment is carried out under conditions of constant volume, we are measuring AE. Your answer should be in k]/mol and entered to 3 sig. fig. 120...

Thermometer Ignition wires heat sample Stirrer 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. Water In the laboratory a student burns a 0.423-g sample of bisphenol A (C5H1602) in a bomb calorimeter containing 1120. g...

Specific Heat Capacity A 21.5-g sample of an unknown metal is heated to 94.0°C and is placed in a insulated container containing 128 g of water at a temperature of 21.4°C. After the metal cools, the final temperature of the metal and water is 25.0°C. Calculate the specific heat capacity of the metal, assuming that no heat escapes to the surroundings. Heat loss=Heat gained. Specific Heat Capacity of water is 4.18 J/g/K in this temperature range. Submit Answer Incompatible units....

I don't know why the last two are
wrong.
To calibrate your calorimeter cup, you first put 47 mL of cold water in the cup, and measure its temperature to be 25.9 °C. You then pour 49 mL of hot water, temperature = 49.9 °C, into the cup and measure the temperature every thirty seconds over a 10 minute period. You extrapolate this "cooling curve" back to the time of addition and find that the "final temperature" after mixing is...
A 2.47 g sample of caffeine
(C8H10N4O2) burns in a
constant-volume calorimeter that has a heat capacity of 7.86 kJ/K.
The temperature increases from 297.65 K to 305.65 K. Determine the
heat (qv) associated with this reaction.
Now use the data above to find ΔE for the combustion of one mole
of caffeine.
