What are the combustion phenomena of carbon in air and oxygen?
In the air: continuous red heat, produce colorless, can make clear limewater turbid gas
In oxygen: white light, heat, colorless and turbid gas
The reason why carbon burns more vigorously in oxygen than in air
The oxygen content in the air is 21%, which is lower than that of pure oxygen
In dry air, the volume of oxygen accounts for about 21%. The volume of nitrogen accounts for about 78%?
Oxygen content: 600x21% = 126m3
Nitrogen content: 600x78% = 468m3
