Answer:
The formula is Ek= CΔt
C is the heat capacity of the bomb calrimitor (sometimes given in question so don't worry, or you may be given the other variables and be expected to find C)
T is the temperature (initial and final)
1. Find the E absorbed (released) by the container. Ek= CΔt
2. Use the Principal of heat transfer.
Ep reaction = -Ek calorimeter
3. Find E released (absorbed) by the reaction.
(Ep = nΔΗ)
