Question

You are conducting the following reaction to prove the Law of Conservation of Mass:
Hi + HCO3() → H20(1) + COz(g)
What container should you conduct this reaction in?
(1 point)
• Plate
Sealed Jar
Glass Bowl
• Any type of glass container

Answer 1

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

A sealed jar will prevent the escape of gases (like \( \text{CO}_2 \)), allowing you to measure the mass of the system before and after the reaction accurately. In contrast, a plate or an open container like a glass bowl would allow gas to escape, which would lead to a loss of mass and could distort your results. Any type of glass container might not be ideal if it's not sealed, as gases could escape. Therefore, the sealed jar is the best choice.
