when their is the word ide at the end of an equation for example : Zinc Sulfide - does it refer to the sulfide or sulfate? what is the equation for that element?

An "ide" suffix means that the anion is just a simple element, such as sulfur in Zinc Sulfide = ZnS
"Ate" and "ite" represent polyatomic ions, ususally containing oxygen.
SO4 = sulfate and SO3 = sulfite
additional details
Br = bromide
BrO= hypobromous
BrO2 = bromous
BrO3 = bromic
BrO4 = perbromic

The -ide suffix refers to elements (that have negative ions). Therefore, zinc sulphide is ZnS. The -ate suffix is used for polyatomic ions (usually contain oxygen) where the central atom has the highest oxidation number, if there is another similar ion with the same central atom. For example, SO4 and SO3. SO4 is sulphate because the oxidation number of sulphur here is +8 while SO3 is sulphite because the oxidation number of sulphur here is +6.
