Homework Help: chemistry

Posted by sari on Wednesday, October 12, 2011 at 10:56am.

1)
MgO (s) + 2H (aq) -> Mg+2 (aq) + H2O (l)

2)
Mg+2 (aq) + H2 (g)-> Mg(s) + 2H+ (l)


3) equation 1+ equation 2 =

MgO (s) + H2 (g) -> Mg (s) + H2O (l)


is it correct?

if so, i need to write an expression which could be used to obtain the heat of formation of magnesium oxide (delta Hf MgO)


thanks
