Question

Write a word equation for the overall reaction that occurred in the baggie. The reactants are sodium bicarbonate and calcium chloride. The products are sodium chloride, calcium carbonate, carbon dioxide, and water. Write a balanced formula equation for the overall reaction that occurred in the baggie.

Answer 1

The balanced chemical equation for the reaction between sodium bicarbonate and calcium chloride, forming sodium chloride, calcium carbonate, carbon dioxide, and water, is 2 NaHCO3(aq) + CaCl2(aq) → 2 NaCl(aq) + CaCO3(s) + CO2(g) + H2O(l).

Step-by-step explanation:

The overall reaction between sodium bicarbonate and calcium chloride involves a double displacement reaction which can be written as a word equation:

Sodium bicarbonate + Calcium chloride → Sodium chloride + Calcium carbonate + Carbon dioxide + Water

When writing the balanced chemical equation, we first write the unbalanced equation:

NaHCO3(aq) + CaCl2(aq) → NaCl(aq) + CaCO3(s) + CO2(g) + H2O(l)

Then we balance it to make sure that there are equal numbers of each type of atom on both sides of the equation:

2 NaHCO3(aq) + CaCl2(aq) → 2 NaCl(aq) + CaCO3(s) + CO2(g) + H2O(l)
