The combustion of titanium with oxygen produces titanium dioxide: Ti (s) + O 2(g) → TiO 2 (s) When 0.610 g of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 25.00 °C to 50.50 °C. In a separate experiment, the heat capacity of the calorimeter is measured to be 9.84 kJ/K. The heat of reaction for the combustion of a mole of Ti in this calorimeter is ________ kJ/mol.

The value of ΔH° for the reaction below is -126 kJ. The amount of heat that is released by the reaction of 45.0 g of Na 2O 2 with water is ________ kJ. 2Na 2O 2 (s) + 2H 2O (l) → 4NaOH (s) + O 2 (g)
