What is the chemical formula for the compound formed between vanadium(iii) and the bromate ion?

Explanation:

Hello,

In this case, vanadium is specified with +3 as its oxidation state, however it is stated that vanadium is combined with the bromate ion, which according to the IUPAC rules, accounts for bromine's last oxidation state, that is +5, in such a way, we build up the bromate ion forming the bromic acid shown below:

Such bromate comes from the bromic acid's anion, this is , thus, the required formula of the vanadium (III) bromate turns out into:

Best regards.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
