-Al₂O₃ is the raw material for manufacturing aluminum and must be heated considerably before it can be converted to aluminum. Calculate the amount of heat (in kJ) required to heat 200 kg of Al₂O₃ (C = 79.04 J/molK) from 25°C to 1000°C and compare that to the amount of heat required to heat 200 kg of Al metal (C = 24.35 J/molK) from 25°C to 550°C. What is the difference?

A) 9.25 x 10⁵ kJ
B) 9.47 x 10⁴ kJ
C) 7407 kJ
D) 79.04 kJ
E) 1961 kJ
