titanium(IV) sulfite Ti2(SO3)4 = Ti(SO3)2 ; reduce the ratio ionic compound (metal + nonmetal) transition/heavy metals require roman numerals to indicate charge because they have more than one type of charge.
NO2 nitrogen dioxide molecular compound (nonmetal + nonmetal)- use prefixes mono is not used on the cation, or the first element of the compound.
P4O10 tetraphosphorus decoxide molecular compound- use prefixes decaoxide becomes decoxide because of the double vowels "a" then "o".
