define standard heat of formation (^H°f)of (MgCO3)
Fri, 2010-03-12 03:16
The energy change that occurs when 1 mole of a substance is made from its elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 degrees Celsius)
eg for CuSO4 it would be
Cu(s) + S(s) + 2O2(g) -----> CuSO4(s)

So its Mg(s) + C (s) + O2(s) --> MgCO3 ?

The equation needs to be balanced. Oxygen is a gas
Mg(s) + C (s) + 3/2 O2(g) --> MgCO3(s)
