An unknown mineral is placed in a bomb calorimeter for analysis.
The geologist wants to find out how much heat is released during the
combustion of this unknown material. This will help her to
understand the stability of this mineral under certain temperature
conditions. She places a 1.2 g sample into the bomb calorimeter
which holds 800 g of water. The temperature within the calorimeter
raises from 24.5 °C to 32.6 °C. The C for the calorimeter is known
at 830 J/°C. Find the q, in k), of the reaction for this sample of
teria
