Question

Quizplus · Accepted Answer

The balanced equation for the given reaction is NaHCO₃ → Na₂CO₃ + CO₂ + H₂O. In order to balance this equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.

On the reactant side, we have 1 Na, 1 H, 1 C, and 3 O atoms. On the product side, we have 2 Na, 1 C, 3 O, and 1 H atoms. To balance the equation, we need to place a coefficient in front of the reactant and/or product that will equalize the number of atoms for each element.

Starting with Na, we can balance the sodium atoms by placing a coefficient of 2 in front of NaHCO₃ to give us 2 Na on the left-hand side of the equation. This gives us 2 Na on both sides of the equation.

Next, we can balance the carbon atoms by placing a coefficient of 1 in front of Na₂CO₃ to give us 1 C on both sides of the equation.

Then we can balance the oxygen atoms by placing a coefficient of 2 in front of NaHCO₃ to give us 2 H, 2 C, and 6 O atoms on the left-hand side of the equation. This gives us 2 H, 1 C, and 3 O atoms on the right-hand side of the equation.

Finally, we can balance the hydrogen atoms by placing a coefficient of 2 in front of H₂O to give us 2 H on both sides of the equation.

The resulting balanced equation is: 2 NaHCO₃ → Na₂CO₃ + CO₂ + 2 H₂O. The corresponding coefficients are 2: 1: 1: 2, which are equivalent to the coefficients in choice C. Therefore, the best choice is C.
