The combustion of titanium with oxygen produces titanium dioxide:

Ti (s) + O2 (g) ?→? TiO2 (s)

  1. When 0.610 g of titanium was combusted in a calorimeter, the temperature of the calorimeter increased from 25.00 ?°?C to 28.00 ?°?C. What is the heat capacity of the calorimeter? ?Δ?H?°?f to TiO2 is -945 kJ/mol
  2. This same calorimeter is used to determine the energy of walnuts. A 1.045 g sample of walnut was combusted in the same calorimeter. The temperature changed from 22.00 ?°?C to 30.90 ?°?C. Calculate the kcal (Cal) per ounce of walnut
