iron reacts with calcium sulfate

Hi, I all I can see is "iron reacts with calcium sulfate". I would be happy to try to answer if you post the rest of the problem.

Was the question what reaction occurs between Iron (Fe) and Calcium sulfate CaSO4? If so, which Iron is reacting? I'm assuing it's just going to look like this:

 

X1Fe + X2Ca(SO4) ->  X3Ca + X4Fe(SO4)

 

Then you'll just need to solve for X1...X4 (which should be easier than you'd think for this particular equation).

Account for the charge of the ions. Fe stands for iron and Ca is calciumFe  and Ca is + charged

So4 (sulfate) has a charge of -2

So it will be written as Fe + Ca(So)4 [-2] --- > Fe(So)4 + Ca

If the charge of the sulfate  is -2, that will be transferred to the iron 

Fe + Ca(So)4 [-2] --- > Fe2(So)4 + Ca

All you have to do now is balance the equation. Look at the coefficient of each element and make sure the number of moles for Fe, iron, for example, is the same as the reaction side (left side) as in the product (right side)

Fe + Ca(So)4 [-2] --- > Fe2(So)4 + Ca

Illustration: the coefficient for Fe on the left side is 1 while on the right side, it is 2. To balance out the molar ratio for both sides, add 2 on the left side:

2Fe + Ca(So)4 [-2] --- > Fe2(So)4 + Ca
