A chemist performs the reaction #6ClO_2 + 3H_2O -> 5HClO_3 + HCl#. If a chemist wants to make 50.0 g of #HClO_3#, what is the minimum number of grams of #ClO_2# that she can use?
And for both half-equations, mass and charge are conserved. And so we take
And we cancel common reagents....
The which I think is balanced with respect to mass and charge.
And so (finally!) we want a molar quantity with respect to
And so with respect to
