Question: The gas that can best be collected by downward displacement of air is?
The gas that can best be collected by downward displacement of air is a gas that is denser than air. When a gas is collected by downward displacement, it means that the gas is allowed to flow downwards into a container, displacing the air that was previously in the container.
Since gases have different densities, some gases will naturally sink to the bottom of a container and displace the air, while others will rise to the top and mix with the air.
One example of a gas that can be collected by downward displacement of air is carbon dioxide (CO2). Carbon dioxide is denser than air, and will therefore sink to the bottom of a container when it is released.
Other gases that are denser than air and can be collected by downward displacement include sulfur dioxide (SO2) and hydrogen chloride (HCl).
It is important to note that when working with gases, appropriate safety measures should be taken to avoid inhaling or exposing oneself to potentially harmful gases.
