The combustion of titanium with oxygen produces titanium dioxide:
Ti(s)+ $\mathrm { O } _ { 2 }$ (g)? $\mathrm { TiO } _ { 2 }$ (s)
When 2.090 g of titanium is combusted in a bomb calorimeter,the temperature of the calorimeter increases from 25.00 °C to 91.30 °C.In a separate experiment,the heat capacity of the calorimeter is measured to be 9.84 kJ $\mathrm { K } ^ { - 1 }$ .The heat of reaction for the combustion of a mole of Ti in this calorimeter is ________ kJ $\mathrm { mol } ^ { - 1 }$ .

Quizplus · Accepted Answer

The heat absorbed by the calorimeter is calculated using q = C × ΔT, where C is the heat capacity and ΔT is the temperature change. The heat of reaction is then calculated per mole of Ti, considering the molar mass of Ti and the heat absorbed.
