Question

What is the name of the compound Sn(CO3)2?

Answer 1

First, do you know the names of the atoms/ polyatomic ion?
Sn =
CO\(_3\) =

Nomenclature begins with the cation first (positive charge), followed by the anion (negative charge).
Then, find the oxidation state.
CO\(_3\)\(^{2-}\) - better known as carbonate.
To find the oxidation state of Sn, I like to use an equation:

\(\sf \color{red}{x}\) represents the \(Sn\) atom.
So you have: \(\sf \color{red}{x}\) + [\(-4\)] = 0
solve for \(\sf \color{red}{x}\)!

Now, where did I get the -4 from? Well, you have TWO carbonate ions! Look at your formila: (CO\(_3\))\(\sf \color{red}{_2}\)
And if you have two -2 charges, -2 + -2 = -4

Answer 2

So you have: cation (\(\sf \color{red}{x}\)) anion
however, \(\sf \color{red}{x}\) is written in roman numeral, For instance, you have iron (III) oxide, which is
Fe\(_3\)O\(_4\)

Answer 3

Tin (IV) Carbonate.

Answer 4

Ok...
