5.00g of metal X is reacted in a bomb calorimiter containing 50.0ml of DiH2O. After the temperature has stabilized, the water temp raises from 20.1C to 22.4C. What is the Q for the reaction? What is the H for the reaction? Basically I need to know what Q= and what H =.

Homework Answers

Answer #1

Density of water is 1 gm/ml

50 ml of water = 50 gm mass

Specific heat of water is = 4.2 Jgm-10C-1

Q = mST

Q = 50 4.2 (22.4 - 20.1)

Q = 483 J

Bomb calorimiter tells us about the change in internal energy

E = 483 J

But without writing the equation we can not find  ng
