Question

Na + H20 -> NaOH+ H2 ( balance the equation in algebric method​

Answer 1

Answer:

Balancing the given equation

Na + H2O –> NaOH + H2

Following are the easy steps to balance the equation:

Step 1: Write the Unbalanced Chemical Equation Let us consider an unbalanced equation

Na + H2O –> NaOH + H2

Step 2: Write Down Number of Atoms Write down the number of atoms of each element present on both reactant as well as product side

Atom Reactant side Product side

Na 1 1

H 2 3

O 1 1

Step 3: Add Coefficients To Balance the Mass in a Chemical Equation Note that the coefficients that are to be added must be a whole number and one coefficient added applies to all the atoms present in that one particular molecule.

2Na+2H2O—> 2NaOH+H2

After balancing the equation we get the number of reactants and products as given in the table

Atom Reactant side Product side

Na 2 2

H 4 4

O 2 2

Since the number of atoms is equal on both the side of the equations, the given chemical equation is balanced.

Hence the balanced chemical equation is

2Na+2H2O—> 2NaOH+H2
