//**1) Given:**// Al(OH)3 //**Name:**// Aluminium Hydroxide This is an ionic compound. The charge of the polyatomic ion is -1 and since there are 3 of them, the charge is -3.

This is an acid compound. I used Rule #1. The reason is that the prefix hydro- is used.
 * //2) Given://** hydrofluoric acid **//Formula://** H2F

//**3) Given:**// H3(PO4) //**Name:**// Phosphuric Acid This compound is an acid. I used Rule #3. The reason is that the suffix -ate​ is being used.



//**4) Given:**// Lead(IV) Phosphate //**Formula:**// PbP4 This is an ionic compound. The reason is that there is a transition metal.
