Compound Molecule | |||
Law of Conservation of Mass | States that mass is neither created nor destroyed in any ordinary chemical reaction | Chemical Equation | It is the symbolic representation of a chemical reaction where the reactant entities are given on the left hand side and the product entities on the right hand side. |
Physical Change | It doesnt produce a new substance. Changes the things state or phase | Chemical Reaction | It is a process that leads to the transformation of one set of chemical substances to another |
