Hydrogen, nitrogen, oxygen, and carbon dioxide are all gases at room temperature.<\/section>\n
At standard room temperature (around 20-25 \u00b0C) and pressure (1 atm), Hydrogen (H\u2082), Nitrogen (N\u2082), Oxygen (O\u2082), and Carbon Dioxide (CO\u2082) all exist in the gaseous state.<\/section>\n
Option A is incorrect because while H\u2082, N\u2082, and O\u2082 are diatomic, CO\u2082 is triatomic. Option C is incorrect because all four gases are colourless. Option D is incorrect because they have vastly different reactivities (e.g., flammability, ability to support combustion, inertness).<\/section>\n","protected":false},"excerpt":{"rendered":"
