Explanation of Solution

Introduction:

In balance equation, reactant and product will have same number of coefficient. Chemical reactions can be explained in a precise way through chemical equations.

The given reaction is HCl(aq)+Na2CO3(aq)NaCl(aq)+H2O(l)+CO2(g)

Here, in this reaction, all atoms are balanced except Na and H .

Balance Na on the product side by multiplying NaCl with 2.

HCl(aq)+Na2CO3(aq)2NaCl(aq)+H2O(l)+CO2(g)

So, Na is balanced on both the reactant and product side.

Now, balance H and Cl on reactant side by multiplying HCl with 2,

2HCl(aq)+Na2CO3(aq)2NaCl(aq)+H2O(l)+CO2(g)

Thus, the balance reactant is,

2HCl(aq)+Na2CO3(aq)2NaCl(aq)+H2O(l)+CO2(g)

Conclusion:

Hence, the balanced equation is 2HCl(aq)+Na2CO3(aq)2NaCl(aq)+H2O(l)+CO2(g) .
