What mass of carbon dioxide can be made by reacting 1.56 grams of sodium bicarbonate with 0.687 grams of hydrochloric acid? NaHCO₃(s)+ H⁺(aq)→ CO₂(g)+ H₂O(l)+ Na⁺(aq)

To solve this problem, we need to use stoichiometry to determine the amount of carbon dioxide produced from the given masses of sodium bicarbonate and hydrochloric acid.

First, we need to write a balanced chemical equation for the reaction:

NaHCO3(s) + HCl(aq) → CO2(g) + H2O(l) + NaCl(aq)

From the equation, we can see that the ratio of sodium bicarbonate to carbon dioxide is 1:1. That means if 1.56 g of sodium bicarbonate is used, then 1.56 g of carbon dioxide will be produced.

Next, we need to determine the limiting reactant, which is the reactant that will be completely used up in the reaction. To do this, we need to calculate the amount of carbon dioxide that would be produced if all of the hydrochloric acid reacted:

0.687 g HCl × (1 mol HCl/36.46 g) × (1 mol CO2/2 mol HCl) × (44.01 g CO2/1 mol CO2) = 0.418 g CO2

Since the amount of CO2 produced from the hydrochloric acid is less than the amount produced from the sodium bicarbonate, the hydrochloric acid is the limiting reactant.

Finally, we can calculate the mass of carbon dioxide produced by using the mass of the limiting reactant:

0.687 g HCl × (1 mol HCl/36.46 g) × (1 mol CO2/2 mol HCl) × (44.01 g CO2/1 mol CO2) = 0.418 g CO2

The answer is closest to choice C) 0.817 g, which is the mass of CO2 produced from the sodium bicarbonate. Therefore, the best choice is C) 0.817 g.
