Question

Al + H2O = Al2O3 + H2
BALANCE PLS

Answer 1

Given:

$Al+H_2O\rightarrow Al(OH)_3+H_2$

To do:

Balance the given reaction

Solution:

• The given reaction is $Al+H_2O\rightarrow Al(OH)_3+H_2$ . For this reaction the number of atoms in the:

Reactant side

Al = 1

H = 2

O = 1

Product side

Al = 2

O = 3

H = 5

• As the number of atoms in the reactant as well as product side is not equal, the given equation is not a balanced one.
• To balance it certain changes must be made. The given equation with some alteration gives:

$2Al+6H_2O\rightarrow2Al(OH)_3+3H_2$

• When the number of atoms in the above reaction is calculated, it gives:

Reactant side:

Al = 2

H = 12

O = 6

Product side:

Al = 2

H = 12

O = 6

• Thus both the reactants as well as product contains equal number of atoms, the above-given reaction is a balanced reaction.

Conclusion:

Unbalanced equation:  $Al+H_2O\rightarrow Al(OH)_3+H_2$

Balanced equation: $2Al+6H_2O\rightarrow2Al(OH)_3+3H_2$
