    How do you write the balanced equation for Magnesium Carbonate reacting with Sulfuric Acid to produce hydrated magnesium sulfate crystals.

    I think the equation would be:

    7H2SO4 + 7MgCO3 ---> 7MgSO4(dot)7H2O + 7CO2

    but just wanted to check its right

    The H2SO4 is a solution, the waters of crystalisation come from the "solvent", i.e. water.

    Therefore 7H2O would form (and add to the existing water).

    Then, why not divide throughout by seven.

    The water of crystalisation would only become associated in the crystal when the solution were evaporated.

    Okay thank you, its just because in the question it said Magnesium Sulfate was MgSO4.7H2O
