molecular form

​

Answer 1

Answer:

I think they represent by their atomic form..

The relationship between reactants and products in a chemical reaction can be represented by a chemical equation that has this general form: Reactants → Products. The arrow (→) shows the direction in which the reaction occurs. In many reactions, the reaction also occurs in the opposite direction.

Chemical reactions are represented by Chemical Equations. Chemical equations are balanced to show the same number of atoms of each element on each side. In chemistry there is a Law called the Law of Conservation of Mass that states that matter cannot be created nor destroyed.
