The structure of the compound or molecule predict the name of compound. given the binary molecule hcl, which statement does not follow the iupac nomenclature rules? a) the hydrogen cation indicates that the compound is an acid. b) the two nonmetals indicate that covalent naming rules apply. c) the name of the anion predicts the name of the final molecule. d) the lack of oxygen in the anion indicates the prefix "hydro-" is used.

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 !

b. is the answer hoped i
