Explanation:
heat released by the solution
= 120 x 3.18 x ( 25 - 14 )
= 4197.6 J
= 4.1976 kJ
This is the heat gain by the salt
so enthalpy change = + 4.1976 kJ
because there is increase in enthalpy
It is endothermic process .
Most of the substances found on earth are compounds.
(water is made up of 2 elements)
(a baseball is larger than a golf ball by default)
