    Format chemical elements and formulas correctly.

    Superscript charges and subscript numbers.

    Example: CO3- ; Na+

    Write chemical elements and formulas correctly

    For example Na refers to sodium not NA. CO2 refers to carbon dioxide not Co2

    Do not use equal signs when writing a chemical reaction use single sided arrow for reactions where products completely dissociate or double sided arrow for reactions that are in equilibrium

    Example HCl —> H+ + Cl- is correct but Cl = H+ + Cl- is incorrect. Remember that chemical reactions are not mathematical equations.

    Balance chemical reactions. When you write a chemical reaction ensure that it is balanced.

    Add placeholder zeros to numbers. For example 0.5 rather than .5
