    okay word equations now can u solve it into the scientific way?:confused:

    First, look up the molecular formulas for the following. I'll do the first, you do the rest.

    Aluminum Bromide -
    Chlorine
    Aluminum Chloride
    Bromine

    Once you have that, put a double-headed arrow between the reactants (put on the left side) and the products (put on the right side). Put "+" signs between them. Once you have that written down, you proceed to balance the equation.

    For example, if I had the following "word problem"

    sodium bicarbonate plus hydrochloric acid react to form sodium chloride, water, and carbon dioxide

    I would do the following

    sodium bicarbonate =
    hydrochloric acid =
    sodium chloride =
    water =
    carbon dioxide =

    then



    I can see that I have two sodiums on the left, so I put two on the right



    Now, I need two chlorines on the left, so it becomes



    Interestingly, that gives me two hydrogens that I need for the water, and the carbons and oxygens also are balanced, so the work is done.
