For the two equations given below:
`H_(2)(g)+1//2O_(2)(g)toH_(2)O(l)+x_(1)kJ`
`H_(2)(g)+1//2O_(2)(g)toH_(2)O(g)+x_(2)kJ`
Select the correct answer:

For the two equations given below : H_2(g) + 1/2 O_2(g) to H_2O(l) + x_1 kJ H_2(g) +1/2 O_2 (g) to H_2O(g) + x_2 kJ Select the correct answer(s)

H_(2)O(g)+(1)/(2)O_(2)(g)toH_(2)O(g)," "DeltaH=x H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(l)," "DeltaH=y heat of vaporization of water is:

The enthalpy of the reaction H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(g) is DeltaH_(1) and that of H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(l) is DeltaH_(2) . Then

The enthalpy of the reaction H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(g) is DeltaH_(1) and that of H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(l) is DeltaH_(2) . Then

H_2(g) + 1/2 O_2(g) to H_2O (l), DeltaH = - 286 kJ 2H_2(g) + O_2(g) to 2H_2O (l), DeltaH = …kJ

Assuming experimental conditions are the same, compare (DeltaH-DeltaU) values for the gives reaction: (1) H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(l) (2) H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(g) .

The free energy change for the following reactions are given below C_(2)H_(2)(g)+(5)/(2)O_(2)(g)to2CO_(2)(g)+H_(2)O(l) , DeltaG^(@)=-1234 kJ C(s)+O_(2)(g)toCO_(2)(g) , DeltaG^(@)=-394 kJ H_(2)(g)+(1)/(2)O_(2)(g)toH_(2)O(l) , DeltaG^(@)=237 kJ What is the standard free energy change for the reaction H_(2)(g)+2C(s)toC_(2)H_(2)(g) ?
