Question

Fill in the coefficients that will balance the following reaction: a0Na + a1H2O → a2NaOH + a3H2

Answer 1

Answer : The balanced chemical reaction will be,

$2Na+2H_2O\rightarrow 2NaOH+H_2$

Explanation :

Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

The given unbalanced chemical reaction is,

$a_0Na+a_1H_2O\rightarrow a_2NaOH+a_3H_2$

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of hydrogen are not balanced while all the atoms are balanced.

In order to balanced the chemical reaction, the coefficient 2 is put before the $Na,H_2O\text{ and }NaOH$

Thus, the balanced chemical reaction will be,

$2Na+2H_2O\rightarrow 2NaOH+H_2$

Answer 2

Hey there !  :

2 Na + 2 H2O = 2 NaOH + 1 H2

Sodium + Dihydrogen Monoxide = Natriumhydroxid + Hydrogen

Coefficients:

Reagents  :  Na = 2
                    H2O = 2
   

Products :  NaOH = 2
                  H2 = 1
