Answer:
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
