    a carbonate of metal has the formula X2CO3 .the equation for the reaction of X2CO3
    a carbonate of metal X has the formula X2CO3 . The equation for the reaction of X2CO3 with HCl is ; X2CO3 + 2HCl - 2XCl +C02 + H2O... 0.245g of the carbonate was found exactly neutralise 23.6cm cubed(to the power 3) of HCl with a concentration of 0.150 mol / dm(TO THE POWER 3 / CUBED) 1) calculate the number of moles of HCl 2) calculate the number of moles of X2CO3 3)calculate the relative molecular mass of X2CO3 4) calculate the relative atomic mass of X and then state which element it is...
