# Given NaHCO_3(aq) + HCl(aq) rarr CO_2(g)uarr + NaCl(aq) + H_2O(l).. what is the stoichiometric ratio between sodium chloride and sodium bicarbonate?

$N a H C {O}_{3} \left(a q\right) + H C l \left(a q\right) \rightarrow C {O}_{2} \left(g\right) \uparrow + N a C l \left(a q\right) + {H}_{2} O \left(l\right)$
Mass and charge are balanced, so this is reasonable, and it specifies a molar equivalence of 1:1 with respect to $N a C l : N a H C {O}_{3}$; i.e. there is a $1 : 1$ stoichiometry....What about with carbon dioxide and hydrogen chloride?
