Copper (II) sulphate reacts with barium chloride according to the equation below.
$CuSO(aq)+BaCl_2(aq)toCuCl_2(aq)+BaSO_4(s) ; DeltaH =-17.7 kJmol^-1$
Calculate the temperature change when $900cm^3$ of 1M copper (II) sulphate were added to 600 $cm^3$ of 1M barium(II)chloride.(Assume
heat capacity of solution is $4.2Jg^-1K^-1$ and density is 1g $cm^-3$ )
