Some compounds names and formulas you just have to memorize. So sulfuric acid is H2SO4, nitric acid is HNO3. For ionic compounds, the name tells you the elements in the compound, but you'll have to just learn the formulas for a bunch of different ions. So, zinc hydroxide is Zn(OH)2. Ammonium sulfide is (NH4)2S. The subscript numbers must be correct to give you an uncharged compound. Zinc (II) iodide is ZnI2.
I would encourage you to make a bunch of flash cards of the ions in the list so that you learn the formulas and charges of the ions. Then you can put them together to make the formulas for these compounds.

1) The ending -ide usually means 2 elements in the compound: Iron III oxide is Fe2O3. The Roman Numeral in the name gives the oxidation number of the first element.
2) The ending -ate usually refers to a polyatomic ion in the
compound: Magnesium phosphate is Mg3(PO4)2. In each case the sum of the oxidation numbers must be 0.
3) Acids ending in -ic also refer to a polyatomic ion: Sulfuric acid is H2SO4
4) If you spot the Greek prefixes mono, di, tri, tetra, penta, use them for your subscripts: dinitrogen pentoxide becomes N2O5

there isnt really anyway of writing equations for these compunds as these are just systematic names, for example you just have to memorise that sulphuric acid is H2SO4, there is no way from the name you can write a formula. There are other names tho, which arent systematic, which give u the shape and therefore formula of a compund, for example 2-methylbutanol or something like that

They're numbers and letters. :)
