NaHCO3 + HCI = CO2 + H2O + NaCl molar ratio

Question

I know the molar ratio of NaHCO3 and CO2 is 1:1 but I don't have an explanation on how I got that answer

Answer 1

The molar ratio comes from the stoichiometric coefficients in the balanced chemical equation. In this example, the coefficient in front of each chemical formula is 1 when the equation is balanced. So, here, the molar ratio between any two substances would be 1:1
