Identification of Gas by Behavior with a Glowing Splint
When trying to identify a gas, one common method is to observe its behavior in the presence of a glowing splint. Different gases exhibit different reactions, which can provide clues about their identity. In this case, we are looking for a gas that will neither burn itself nor cause the splint to burn.
Options:
a) Oxygen
b) Nitrogen
c) Hydrogen
d) Methane
Explanation:
Oxygen:
Oxygen is a highly reactive gas and supports combustion. When a glowing splint is introduced to it, the oxygen in the gas will readily react with the splint, causing it to ignite and burn more vigorously. Therefore, oxygen itself can burn and causes the splint to burn.
Nitrogen:
Nitrogen, on the other hand, is an inert gas and does not readily participate in combustion reactions. It is non-flammable and does not support the burning of other substances. When a glowing splint is introduced to nitrogen, it will not burn or cause the splint to burn. Therefore, nitrogen is the correct answer.
Hydrogen:
Hydrogen is a highly flammable gas. When a glowing splint is introduced to hydrogen, it will ignite and burn with a characteristic pop sound. Therefore, hydrogen itself can burn and causes the splint to burn.
Methane:
Methane is a flammable gas commonly found in natural gas. When a glowing splint is introduced to methane, it will ignite and burn with a blue flame. Therefore, methane itself can burn and causes the splint to burn.
Therefore, out of the given options, only nitrogen is the gas that neither itself burns nor causes the splint to burn.
