The law of conservation of matter states that during a chemical reaction the

Simply stated, the law of conservation of mass means matter cannot be created or destroyed, but it can change forms. In chemistry, the law is used to balance chemical equations. The number and type of atoms must be the same for both reactants and products.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.
