When a 4. 25-g sample of solid ammonium nitrate dissolves in 60. 0 g of water in a coffee-cup calorimeter, the temperature drops from 22. 0 ∘c to 16. 9 ∘c

Sagot :

The amount of heat which is released during the given change is -1,369.68 Joules.

How do we calculate the required heat?

Required amount of heat in any chemical reaction will be calculated as:

Q = mcΔT, where

m = mass = 4.25 + 60 = 64.25g

c = specific heat = 4.18 J/g. degree C

ΔT = change in temperature = 16.9 - 22 = -5.1 degree C

On putting values, we get

Q = (64.25)(4.18)(-5.1) = -1,369.68 J

Hence released heat in the reaction is -1,369.68 J.
