The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that cosplay 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 vày not disappear anywhere và new ones bởi vì not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

| H2SO4 + Ca(OH)2 → H2O + CaSO4 |
| H2SO4 + Ca(OH)2 → H2O + Ca(HSO4)2 |
| H2SO4 + Ca(OH)2 → H2O + Ca(SO4) |
| H2SO4 + Ca(OH)2 → CaSO4 + HOH |
| H2SO4 + Ca(OH)2 → H2O + (CaOH)2SO4 |
| H2SO4 + Ca(OH)2 → H2O + CaOH2SO4 |
