  1. Na2SO4 ==> Na2O + SO3
    The equation is balanced.
    Place a delta sign or write the word "heat" over the arrow. OR it can br done this way.
    Na2SO4 + heat ==> Na2O + SO3
    Some teachers like to write the state (s for solid, g for gas and l for liquid).
    Na2SO4(s) + heat ==> Na2O(s) + SO3(g)
