The Combustion of Titanium with Oxygen Produces Titanium Dioxide

Question 108

Multiple Choice

The combustion of titanium with oxygen produces titanium dioxide:
Ti(s) + O2(g) →TiO2 (s)
When 2.060 g of titanium is combusted in a bomb calorimeter,the temperature of the calorimeter increases from 25.00 °C to 91.60 °C.In a separate experiment,the heat capacity of the calorimeter is measured to be 9.84 kJK-1 .The heat of reaction for the combustion of a mole of Ti in this calorimeter is ________ kJ mol-1.


A) 14.3
B) 19.6
C) -311
D) -0.154
