1.	From the following data. CH_(4)+2O_(2)rarrCO_(2)+2H_(2)O DeltaH^(@)=-890kJmol^(-1) H_(2)O_((l))rarrH_(2)O_((g))DeltaH^(@)=44kJ mol^(-1) " at "298 K Calculate the enthalpy of the reaction CH_(4)+2O_(2)rarrCO_(2)+2H_(2)O ""DeltaH^(@)=?
Answer» Solution :`Ch_(4)+2O_(2)rarrCO2_((g))+2H_(2)O_((l))DeltaH^(@)=-890kJ mol^(-1)` `H_(2)O_((l))rarrH_(2)O_((g))DeltaH^(@)=44kJ mol^(-1) " at " 298K` `DeltaH^(@) " for "CH_(4)+2O_(2_((g)))rarrCO_(2_((g)))+2H_(2)O_((g))` `=-890+44=-846KJ mol^(-1)`
