Answer 1

The correct answer is H2.

Key Points

Hydrogen (H2) is a highly inflammable gas.
It reacts with oxygen (O2) in the air to form water (H2O) while releasing energy in the form of heat and light.
Due to its high flammability, hydrogen is used as a fuel in various applications, including rockets and fuel cells.
In the presence of a spark or flame, hydrogen can combust explosively.

Additional Information

Nitrogen (N2): It is a non-flammable gas that makes up about 78% of the Earth's atmosphere. It is inert under most conditions.
Oxygen (O2): While not flammable itself, oxygen supports combustion and can cause other materials to ignite more easily and burn more vigorously.
Carbon Dioxide (CO2): It is a non-flammable gas that is often used in fire extinguishers due to its ability to suffocate flames.
Safety Measures: Proper storage and handling are crucial for flammable gases to prevent accidents. This includes using appropriate containers and avoiding sources of ignition.
Applications: Flammable gases like hydrogen are used in various industrial processes, including welding, cutting, and as energy sources in fuel cells.
