Answer to Question #264941 in General Chemistry for Treshia

Question

If 4.50 moles of NaHCO3 reacted with 2.40 moles of HCl, 

Take note of the chemical equation: NaHCO3 + HCl → NaCl + H2O + CO2(g)

Answer 1

From the equation,

If 1 mole of NaHCO3 reacts with 1 mole of HCl

Then 4.5moles of NaHCO3 reacts with 4.5moles of HCl.

Since 4.5moles is more than 2.4moles for HCl

Then HCl is the limiting reagent.
