Balancing Chemical Equations

You want to know how to balance chemical equations?
Well it is easy and very simple

First take an equation for e.g.
Al       +         HCl         =        Al3Cl2         +           H2
Name                               the left side we have                                    on the right side we have
H                                               1                                                                              2
Cl                                              1                                                                              2
Al                                              1                                                                              3

We start with the odd one and multiply it to make it balanced on both sides
Here Al is multiplied by 3 in the left side and is balanced
In HCl both H and Cl need 2 to be balanced and hence we multiply HCl by 2
Thus we get
3Al       +       2HCl      =        Al3Cl2         +        H2

In the same way you can solve the other equations.
