Combustion of Carbon Compounds
Combustion of Carbon Compounds
Combustion:
The carbon compounds (including its allotropic forms) burn in oxygen to give carbon dioxide and water vapors. Heat and light are also released during this process. This reaction is called as combustion.
Further, once carbon and its compounds ignite, they keep burning without the requirement of additional energy. That’s why these compounds are used as fuels. Saturated hydrocarbons give a clean blue flame due to their complete combustion whereas, unsaturated hydrocarbons have a yellow flame with lots of black smoke as they do not undergo complete combustion.
The burning of unsaturated hydrocarbons always results in the deposition of soot [a black substance]. However, in the limited supply of air, even saturated hydrocarbons undergo incomplete combustion and give a sooty flame.
Which of the following are correct : (a) Once carbon and its compounds ignite, they keep burning without the requirement of additional energy. (b) Saturated hydrocarbons give a clean yellow flame due to their complete combustion. (c) Unsaturated hydrocarbons have a yellow flame with lots of black smoke as they do not undergo complete combustion. | |||

Students / Parents Reviews [20]
When I have not joined Abhyas Academy, my skills of solving maths problems were not clear. But, after joining it, my skills have been developed and my concepts of science and SST are very well. I also came to know about other subjects such as vedic maths and reasoning.
