The balanced equation is as below
Na2CO3 +2 HCl → 2 NaCl +H2O + CO2
<u><em>Explanation</em></u>
step 1 : write the unbalanced chemical equation
that is Na2CO3 + HCl→ NaCl + H2O +CO2
Step 2: change the coefficient ( <em>number in front of chemical formula) </em>to make sure the number of atoms of an element are the same in both side.
By adding 2 in front of HCl and in front of NaCl balance the equation.
Therefore the balanced equation is as below
Na2CO3 +2HCl → 2NaCl +H2O +Co2

hope this helped :)
Moles=mass/mr(molar mass of CO2 found by adding mass numbers found on periodic table)
= 82/44
=1.86 moles (2d.p)
Hope this helps!
