Answers

Answered by Anonymous

Explanation:

Sometimes gases are collected over water. The gas produced in a reaction is bubbled through a trough of water and into an upturned gas jar filled with water. This works well for insolublegases such as hydrogen, or gases that do not dissolve easily in water, such as oxygen and carbon dioxide.
