Answer 1

To effectively demonstrate the Law of Conservation of Mass for the reaction \( \text{H}^+(l) + \text{HCO}_3^-(l) \rightarrow \text{H}_2\text{O}(l) + \text{CO}_2(g) \), you should conduct this reaction in a **Sealed Jar**.

Using a sealed jar will allow you to capture all the products of the reaction, specifically the carbon dioxide gas, preventing it from escaping into the atmosphere. This way, you can accurately measure the mass before and after the reaction, supporting the principle of conservation of mass. If the container were open (such as a plate or glass bowl), the gas produced could escape, which would lead to a loss of mass and potentially misleading results.
