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