What is a chemical formula GCSE?
The chemical formula shows you the elements involved and the number of atoms involved.
An equation has reactants and products.
Reactants are substances that react together in a chemical reaction to form the products.
Reactants are found before the arrow in a chemical formula and products are found after the arrow.What is c4 in chemistry GCSE?
Conservation of Mass.
The law of conservation of mass says that no atoms are lost or made during a chemical reaction.
This means that the mass of the products equals the mass of the reactants.
Using Moles to Balance Equations.Relative formula mass is calculated by adding up the atomic masses of all the atoms in a molecule or formula unit.
The atomic masses of the elements are taken from the periodic table.
