To identify a gas, I typically observe its physical properties such as color, odor, and whether it is flammable or reactive. I may also conduct a series of tests, such as checking for its solubility in water or using litmus paper to determine acidity or basicity. Additionally, I might use specialized equipment, like gas chromatography or mass spectrometry, to analyze the gas's composition and confirm its identity.
The term gas can not be used to identify a mixture that has the same composition throughout. Gas is a state of matter.
One way to identify a gas in a tube is to perform a flame test. When the gas is burned, it will produce a characteristic color of flame that can help identify the gas. Another method is to use a gas sensor that can detect and analyze the composition of the gas in the tube.
One way to test a gas to identify it as an HCL gas is to dip a glass rod in ammonia and place it in the gas. If a white smoke is produced, the gas is HCL gas.

"NN" is not a recognized chemical symbol for any gas. If you provide more context or clarification, I can help you identify the gas you are referring to.

This depends on the gas and concentration; many tests exist based on the reaction of gas with a specific reagent.
