The coefficients show the number of particles (atoms or molecules), & the indices show the number of atoms that biến hóa the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones vì not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.
