Calculate the enthalpy of combustion of benezene from the following da

1.	Calculate the enthalpy of combustion of benezene from the following data:- (i)6C(s) + 3H_(2)(g) rarr C_(6)H_(6) (l), DeltaH =49.0 kJ mol^(-1) (ii) H_(2) (g) + (1)/(2) O_(2)(g) rarrH_(2)O(l), DeltaH = - 285.8 kJ mol^(-1) (iii) C(s) + O_(2) (g) rarr CO_(2)(g) , DeltaH = - 389. 3 kJ mol^(-1)
Answer» SOLUTION :Aim `: C_(6)H_(6) (L) + (15)/(2) O_(2)(g) rarr 6CO_(2)(g) +3H_(2)O(l) , DeltaH = ?` `6 xx `Eqn. (ii)`+ 3 xx `Eqn. (ii) `- `Eqn. (i) gives the REQUIRED result.
