The combustion of titanium with oxygen produces titanium dioxide: ti (s) + o2(g) â tio2 (s) when 1.000 g of titanium is combusted in a bomb calorimeter, the temperature of the calorimeter increases from 25.00 â°c to 60.00 â°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 heat of reaction for the combustion of a mole of Ti in this calorimeter is -16,557.69 kJ/mol.

Explanation:

Mass of  titanium = 1.000 g

Moles of titanium =

Heat capacity of the calorimeter ,c= 9.84 kJ/K

Initial temperature of the calorimeter ,T=25°C =298 K

Final temperature of the calorimeter ,T'= 60°C = 333 K

Heat gained by calorimeter = q

Heat of combustion released when 1 g of titanium = -344.4 kJ

Heat if released that is why negative sign is used.

In 1 g of titanium = 0.0208 mole

Heat of combustion of 0.0208 moles of titanium = -344.4 kJ

Heat of combustion of 1 moles of titanium:

The heat of reaction for the combustion of a mole of Ti in this calorimeter is -16,557.69 kJ/mol.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
