Question

What happens when a glowing splinter is introduced in a jar containing oxygen?

Answer 1

Combustion

• When a chemical combines with oxygen gas, energy is released in the form of light and heat.
• The presence of oxygen gas as a reactant in combustion processes is required.
• Example: Water vapor is produced by the combustion of hydrogen gas.
• The reaction is as follows:

$2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)$

In a jar, a glowing splinter is introduced

• When a blazing splinter is placed into an oxygen-filled jar, the flames rekindle, but the gas does not catch fire.
• This is due to the fact that oxygen gas aids in the combustion process.
