For copper, it is an element. It could be both reactant and product. While purifying copper will be the product. But copper would be the reactant in case of preparing hydrogen or copper sulphate salts.

It can be either depending on the reaction. It can be a product of electrolysis of copper with sulfuric acid, or an acid base reaction of copper hydroxide and sulfuric acid. It can react with metals such as zinc.
reactant
This depends on the reaction involved.
In the balanced equation CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4, copper sulfate (CuSO4) is a reactant. It reacts with sodium hydroxide (NaOH) to form copper hydroxide (Cu(OH)2) and sodium sulphate (Na2SO4).
Reactant
sulfur is a reactant
Oxygen is a reactant
product
Reactant- glucose and product- carbon dioxide.
Sugar can be both a reactant and a product, depending on the chemical reaction. For example, in the process of photosynthesis, sugar (glucose) is produced as a product. However, in the process of fermentation, sugar is a reactant that is broken down to produce other products like ethanol and carbon dioxide.
Glucose is a product of photosynthesis and a reactant in cellular respiration.
