Describe the amount (g, moles) of the carbonato complex and the volume and moles of hcl that were used in the first step of the reaction and any observations. give a balanced chemical equation for the reaction occurring at this step. name the new complex ion formed (consistent with iupac standards) and sketch its structure. there are two geometrical isomers possible for this complex, include both in your sketch. which one do you think is more likely to be present in this case? why?

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
