In his experiments, Dalton used gases such as hydrogen, oxygen, nitrogen, carbon dioxide, and methane.
You can find examples of these gases in the atmosphere, as they are naturally occurring. You can also purchase them from scientific suppliers.
While Dalton's experiments used specific gases, you can use any gas that is available to you. However, it is important to understand the properties and behaviors of the gas you are using in your experiments.
It is important to research and understand the properties of different gases in order to determine which ones are suitable for your specific experiments. You can also consult with other scientists or reference materials for guidance.
Yes, it is important to follow proper safety protocols when handling and using gases in experiments. This may include wearing protective gear, working in a well-ventilated area, and properly storing and disposing of the gases.
