reactant
NO substance is classified as reactant or product individually.Reactant is a substance which undergoes chemical reaction to give a new product,which is called product.Example:-Water + Sulphur Trioxide --------> Sulphuric acidHere water and sulphur trioxide are reactants and sulphuric acid is the product.Water can be both a reactant and product.
This depends on the reaction involved.
The correctly written chemical reaction format is "Reactant plus Reactant → Product plus Product." In this format, the reactants are on the left side of the equation, while the products are on the right side, indicating that reactants undergo a transformation to form products. Other variations provided do not follow the standard notation for chemical reactions.
Reactant
sulfur is a reactant
Oxygen is a reactant
product
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.
Reactant- glucose and product- carbon dioxide.
There is no elemental iron (Fe) involved in this reaction, neither as reactant (iron sulphide -FeS- plus oxygen are) nor as product (iron oxide (FeO) plus sulphur dioxide are)
Any
Glucose is a product of photosynthesis and a reactant in cellular respiration.
