Complete and balance the following equations : Al + NaOH +___--->+

Al + 3NaOH  = Al(OH)₃ +3Na

Explanation:

The reaction is given as:

            Al + NaOH  = Al(OH)₃ + Na

This reaction is called a single displacement reaction in which one specie displaces another from a solution.

 To balance the equation:

                aAl + bNaOH  = cAl(OH)₃ + dNa

a, b, c and d are the coefficient that will balance the equation:

     Conserving Al;

                 a = c

     Conserving Na;

                b  = d

     Conserving O;

                 b  = 3c

     Conserving H;

                b = 3c

Let a  = 1, c = 1, b = 3 and d = 3

             Al + 3NaOH  = Al(OH)₃ +3Na
