Enthalpy of Combustion of Methane and Ethane
The enthalpy of combustion of methane and ethane are given as -210 kcal/mol and -368 kcal/mol respectively. This means that when one mole of methane and ethane are burned in excess oxygen, -210 kcal and -368 kcal of heat energy are released respectively.
Enthalpy of Combustion of Decane
To find the enthalpy of combustion of decane, we can use the following equation:
nC10H22 + (13.5n + 5n/2)O2 → 10nCO2 + 11nH2O
Where n is the number of moles of decane.
Using the enthalpy of combustion of methane and ethane, we can calculate the enthalpy of combustion for one mole of decane as follows:
Enthalpy of combustion of one mole of methane = -210 kcal/mol
Enthalpy of combustion of one mole of ethane = -368 kcal/mol
Enthalpy of combustion of one mole of decane = 10(-210) + 11(-368) = -5798 kcal/mol
Therefore, the enthalpy of combustion of decane is -5798 kcal/mol.
Answer: (d) Data is Incomplete
Based on the given enthalpies of combustion of methane and ethane, we can calculate the enthalpy of combustion of decane. However, the correct answer is (d) data is incomplete, as we do not have any experimental data or theoretical calculations for the enthalpy of combustion of decane. Therefore, the calculated enthalpy of combustion of decane is only an estimate and may not be accurate.

Enthalpy of combustion of one mole of methane = -210 kcal/mol
Enthalpy of combustion of one mole of ethane = -368 kcal/mol
Enthalpy of combustion of one mole of decane = 10(-210) + 11(-368) = -5798 kcal/mol
Therefore, the enthalpy of combustion of decane is -5798 kcal/mol.
Answer: (d) Data is Incomplete
Based on the given enthalpies of combustion of methane and ethane, we can calculate the enthalpy of combustion of decane. However, the correct answer is (d) data is incomplete, as we do not have any experimental data or theoretical calculations for the enthalpy of combustion of decane. Therefore, the calculated enthalpy of combustion of decane is only an estimate and may not be accurate.
