### Calorimetry Questions

Do we have to add the heat of the calorimeter with the heat of the reaction to calculate the amount of heat released/absorbed from the reaction? Or is the heat absorbed by the calorimeter negligible?

the heat absorbed by the calorimeter is equal to the heat released by the reaction

### Re: Calorimetry Questions

I think we should add it.
There is an example from my discussion.

20g of Cu at 45 degrees celsius is placed into 10g of water at 90 degree celsius. Find the final temperature.
If the question is set in calorimeter, then q(cu)+q(cal) = -q(H2O)
Because copper and calorimeter absorb heat, so the total heat is added. And it is equal to the heat released by water.
