C4
Stoichiometry
Symbols and Formulae
Subscript numbers are small digits written at the bottom, and represents the number of atoms of that element within the compound. THEY COME AFTER THE SYMBOL OF ELEMENT.
-
Naming ionic compounds
"ate"
3 or more elements, one of which is oxygen
-
Balancing Equations
BOTH SIDES OF A CHEMICAL EQUATION MUST BE EQUAL, as the mass of systems won't be affected by a chemical reaction.
-
Relative atomic mass
-
The number of times heavier an average atom of a specific element is than 1/12 the mass of a carbon-12 atom.
-
The mole
-
Relative atomic mass
The number of times heavier an average atom of a specific element is than 1/12 the mass of a carbon-12 atom.
Mole
One mole of a substance is the mass of the Avogadro constant - 6.02x10^23 atoms, molecules or ions of that particular substance.

Limiting reactants
Most chemical reactions that are carried out do not use the exact amounts of substance predicted by the balanced chemical equation. This is usually because one of the reactants is a limiting factor of process and is used up and so halts the reaction.
Ionic Compounds
To calculate out how to write the subscripts, first find positive and negative ions, then rotate the ratio to find out the chemical formula
