//__Guide to Writing and Naming Formulas for Chemical Compounds__//

Rules for Naming and Writing Formulas for Acids states that every compound will follow the formula HnX. S would be the X in the formula. Since S would end with -//ide,// the compund would follow Rule #1, when the name of the anion (X) ends in -//ide,// the acid name begins with //hydro-,// has the suffix //-ic,// and is followed by the word acid.
 * __ { Given} H2S - [Name] - Hydrosulfuric Acid __



Rules for Naming and Writing Formulas for Acids also works in the reverse order. Therefore if you follow Rule #3, it states that when the anion name ends in //-ate,// the acid name is the stem of the anion witht the suffix //-ic// followed by the word acid. So because the anion's name ands in //-ic,// it would be an anion ending in //-ate.//
 * __ {Given} Carbonic Acid - [Formula] - H2CO3 __

The formula for Tin(ii) Perchlorate would be Sn(ClO4)2 because the atomic symbol for Tin is Sn, Perchlorate is ClO4, and it has a charge of 2-. So to balance the charge, Tin's charge would have to be 2.
 * __{Given} Tin(ii) Perchlorate - [Formula] - Sn(ClO4)2__
