Explain properties of compound by taking CO2 as
an example
Answers
Answer:
Physical Properties of Carbon:
Carbon is a unique element. It occurs in many forms. Some of the examples of the pure form of carbon are coal and soot.
It is soft and dull grey or black in color.
One of the most important compounds of carbon is the charcoal, which is formed when carbon is heated in the absence in of air.
It occurs in a number of allotropic forms. Allotropes are nothing but forms of an element with varying physical as well as chemical properties.
The density of the different forms of carbon depends upon the origin of these elements. You will find some forms of carbon which are pure and some forms which are not pure like coal which is the mixture of both carbon and hydrogen.
Chemical Properties of Carbon
Carbon compounds generally show 4 reactions, they are
Combustion reaction
Oxidation reaction,
Addition reactions
Substitution reaction.
As we all know that carbon in all forms needs oxygen, heat, and light and forms carbon dioxide. When it is burned in air to give carbon dioxide, it is called as combustion.
Let us get the concept of this using some examples when it is burnt in the air: When methane CH4 is burnt in the presence of oxygen it gives us carbon dioxide, heat, and light.
Carbon compounds in fuels like diesel
This is because when carbon or diesel is burnt in air, it produces a large amount of heat energy.
Combustion is of two types:
Complete Combustion
Incomplete Combustion
We all have seen cooking gas burning at home, they burn blue in color. Have you ever thought why it appears blue? The answer is that when a saturated hydrocarbon is burnt in the presence of oxygen then it gives blue colour flame and this is because here fuel is burnt completely. In other words, you can understand it by knowing that the percentage of carbon present in saturated hydrocarbons is low and it gets easily oxidised.
