Explanation / Answer

Heating the ice:
T = 0 - (-10) = 10 C

q = mcdT= 866g x 2.03 J/g*C x 10 = 17579.8 J

Melting the ice:
Temperature not required, since it's a phase change from solid to liquid at constant temperature.

q = 866g/18g/mole x 6.02 kJ/mo * 1000 J / 1 kJ = 289628.8 J

Heating the water:
T = 100 - 0 = 100 C

q = 866 g x 4.18 J/g*C x 100 C = 361988 J

Vaporizing the water:
Temperature not required, since it's a phase change from liquid to gas at constant temperature.

q = 866g/18g/mole x 40.7 kJ/mol * 1000 J / 1kJ = 1958122.2 J

Heating the team:
T = 126 - 100 = 26 C

q = 866 g x 1.99 J/g*C x 26 C = 44806.84 J

q(total) = 17579.8 + 289628.8   + 361988 + 1958122.2 + 44806.84

= 2672125.64 J

=2672.1 KJ
