SnBr2 (s) + TiCl2 (s) ------>
SnCl2 (s) + TiBr2
(s) ?rHo = -4.2 kJ/mol
SnCl2 (s) + Cl2 (g) -------->
SnCl4 (l) ?rHo = -195 kJ/mol
TiCl4 (l) ------> TiCl2 (s) +
Cl2 (g) ?rHo = + 273 kJ/mol

SnBr2 (s) + TiCl4 (l) -------->
TiBr2 (s) + SnCl4 (l)
; ?rHonet = -4.2
- 195 + 273 = + 73.8 kJ/mol
heat lost by nickel = heat gained by water
67.50 gms * Cp,nickel * (97.88 - 21.09)oC = 79.45 gms *
4.18 J/gm oC * (27.25 - 21.09)oC
Cp,nickel = heat capacity of nickel = 0.39467 J/gm
