What is the meaning of the Word chemistry

the scientific study of the structure of substances and what happens to them in different conditions or when mixed with each other

The definition of chemistry is a branch of science that deals with the form and properties of matter and substances or the interaction between individuals. An example of chemistry is the study of protons and neutrons. ... The chemical properties, composition, reactions, and uses of a substance.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
