Introduction:
The given information states that a gas at low temperature does not react with most compounds, is almost inert, and is used to create an inert atmosphere in bulbs. Additionally, it mentions that the combustion of this gas is an exceptionally endothermic reaction. Based on this information, we can conclude that the gas is nitrogen (option B).
Explanation:
Inert and Non-reactive:
Nitrogen gas is known to be highly inert and non-reactive under normal conditions. It is a colorless, odorless gas that makes up approximately 78% of the Earth's atmosphere. Nitrogen gas molecules consist of two nitrogen atoms bonded together (N2), and this strong triple bond makes it difficult for nitrogen to react with other compounds. Therefore, it does not readily react with most substances, rendering it inert.
Used to create inert atmosphere:
Nitrogen gas is commonly used to create an inert atmosphere in various industrial processes. Its inert nature makes it suitable for applications where reactivity needs to be minimized or prevented. For example, in light bulbs, an inert atmosphere is required to prevent the filament from oxidizing and burning out. By filling the bulb with nitrogen gas, the oxygen is displaced, creating an oxygen-free environment that prolongs the life of the filament.
Endothermic combustion:
The given information also states that the combustion of this gas is an exceptionally endothermic reaction. Combustion is a chemical reaction that typically involves the rapid combination of a fuel with oxygen, releasing heat and light. However, in the case of nitrogen gas, its combustion reaction is endothermic, meaning it absorbs heat from the surroundings rather than releasing it. This is due to the strong triple bond between the nitrogen atoms, which requires a significant amount of energy to break before the combustion can occur. As a result, nitrogen gas does not readily undergo combustion and is not used as a fuel source.
Conclusion:
Considering the information provided, the gas described is nitrogen. Its inert and non-reactive nature, use in creating an inert atmosphere, and the endothermic nature of its combustion reaction all align with the characteristics of nitrogen gas.
