This is a type of reaction where one atom or group of atoms in a molecule is replaced by another atom or group.
What is substitution?
This is the SI unit of pressure which represents the force of one newton applied over an area of one square meter.
What is a pascal?
These are fundamental particles of matter and are believed to be indivisible building blocks of protons and neutrons.
