What is the Chem Equation for Epsom Salt?

If Epsom Salt is heated too much a gray product is formed and sulfur trioxide gas is given off. What is the balanced equation?

Answers:
MgSO4.7H2O ->MgSO4+ 7H2O
MgSO4 --> MgO + SO3
ow! I tried hard to think but, it hurts too much so, I will have to say, sorry I do not know!(far too early for me!).
no idea

E2SO4

E2SO4 > SO3 + E2O

(Epsom Salts) > (Sulfur Trioxide) + (DiEpsom Oxide)

Good Luck.
MgSO4*7H2O

MgSO4*7H2O(s)--heat-->MgO(s)
+SO3(g)+7H2O(l)
If you remove the water of crystallisation from epsom salts (magnesium sulphate) by heating it, you are left with Magnesium oxide (your grey powder) and sulphur trioxide is given off as a gas.
MgSO4=MgO+SO3
Epsom salt is the common name for hydrated magnesium sulphate. MgSO4.7H2O, (not the anhydrous form). The water of crystalisation is removed by heating to form MgSO4 and then the following reaction takes place.

MgSO4 --------- MgO + SO3
Sodium x chlorine - oxygen
