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.

h let me think

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
