Gnesinka [82]

Answer: 5 moles of  H_2CO_3 can be produced from 5 mol NaHCO3 and 9 mol HCl.

Explanation:

The balanced chemical reaction is:

NaHCO_3+HCl\rightarrow H_2CO_3+NaCl

According to stoichiometry :

1 mole of NaHCO_3 use 1 mole of HCl

Thus 5 moles of NaHCO_3 use=\frac{1}{1}\times 5=5moles  of HCl

Thus NaHCO_3 is the limiting reagent as it limits the formation of product and HCl is the excess reagent.

As 1 mole of NaHCO_3 give = 1 mole of H_2CO_3

Thus 5 moles of NaHCO_3 give =\frac{1}{1}\times 5=5moles  of H_2CO_3

5 moles of  H_2CO_3 can be produced from 5 mol NaHCO_3 and 9 mol HCl.
