This depends on the reaction involved.
Reactant
The reaction Fe(s) → FeS(s) is exothermic because it releases energy. The potential energy of the reactant is higher than that of the product in an exothermic reaction.
product
Reactant- glucose and product- carbon dioxide.
No, it isn't. That is: since it's there as the symbol of an element, and not in a chemical reaction, it's neither a reactant nor a product... it's just a chemical.
reactant
reactant i think because it was in my science book >:-D
This depends on the reaction involved.
sulfur is a reactant
Reactant
The reaction Fe(s) → FeS(s) is exothermic because it releases energy. The potential energy of the reactant is higher than that of the product in an exothermic reaction.
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.
