Reactant(s) are the starting material/chemical to a reactiion Product(s) are the final material/chemical at the end of a reaction.
This depends on the reaction involved.
Reactant
product
The limiting reactant, by definition, will be completely converted to the desired product. If one reactant is substantially more expensive than the other reactant(s), it is monetarily sensible to make the most expensive reactant the limiting one, so that the total material cost per unit of product will be minimized.
Reactant(s) are the starting material/chemical to a reactiion Product(s) are the final material/chemical at the end of a reaction.
Generic format is Reactant ( plus reactant(s)) = Product + (Product(s))
Sugar can be both a reactant and a product.
Sun is a star, not reactant or product.
reactant
This depends on the reaction involved.
A reactant or reactants enters into a chemical reaction to form product(s)

sulfur is a reactant
Reactant
The reactant, because it is reacting to form the product of H2O.
Oxygen is a reactant
