The heat released by the combustion of the naphthalene is mathematically given as

H=2.508975 KJ

Question Parameters:

0.25 g of the organic compound naphthalene

The calorimeter increases from 24.00°C to 26.43 °C.

The calorimeter's heat capacity is 4.13 kJ/°C

Generally, the equation for the Heat released is mathematically given as

H = mCdT

Therefore

H= mC ( T2 - T1)

H= 0.25*4.13 ( 26.43- 24)

H= 2.508975 KJ

In conclusion, the heat released by the combustion of the naphthalene is

H=2.508975 KJ
