Abstract: pH is a unit of measurement often used in fundamental chemistry concepts. “How to Calculate pH” explains it’s categories the scientific mathematics and role pH has in our lives.

Of all the skills to know for chemistry, balancing chemical equations is perhaps the most important to master. So many parts of chemistry depend on this vital skill, including stoichiometry, reaction analysis, and lab work.

The only thing smaller than atoms are their subatomic particles; electrons, protons, and neutrons. Not even under a complex microscopic can we view the individual electrons that surround an atom’s nuclei. The Lewis Dot Structure is a visual which represents the outermost shell of electrons, also known as valence electrons, and possible covalent bonds within an atom or molecule.

Units are extremely important in the study of science. Without them, a number is just a number without any meaning. The Système international d’unités (SI system) is a standard that simplifies international scientific communication. This system comprises seven base quantities and 16 prefixes that designate amount.
