Question
A gas at low temperature does not react with the most of compounds. It is almost inert and is used to create inert atmosphere in bulbs. The combustion of this gas is exceptionally an endothermic reaction. Based on the given information, we can conclude that the gas is
Options
A.oxygen
B.nitrogen
C.carbon mono-oxide
D.hydrogen
Solution
Sol. Nitrogen is chemically inert under ordinary conditions. However, it shows chemical activity under high temperatures. It is used to create inert atmosphere in certain metallurgical atmosphere and used for filling electrical bulbs due to its inertness. Nitrogen combines with oxygen under the influence of high temperature (3000oC) like electric spark.
N2 + O2→2NO
