What is the formula for Tin Oxide?
The formula for Tin Oxide is SnO2 depending on the assigned charge for tin. In this case, the charge assigned to tin was 4.
The formula for tin (IV) oxide is SnO2. This formula shows that each formula unit contains exactly one tin atom. Therefore, if 0.74 mole of tin (IV) oxide is heated sufficiently to cause complete disproportionation of the compound to its constituent elements, 0.74 moles of tin metal will be produced.
That's old-fashioned nomenclature, but that's okay - the "-ic" suffix means you're dealing with tin with a higher number of valence electrons, in this case, 4. So with tin as +4 and oxygen, as always, as -2, you're going to get a formula of SnO2. Tin with a charge of +2 is the other possible valence option, and that's called "stannous oxide" with the "-ous" suffix, and a formula of SnO. The better way to…
