Answer 1

Answer:

The answer is as follows

Explanation:

When Carbon and its compounds burn in the presence of Oxygen (or air), they give CO2, heat and light.The process of burning carbon and its compounds in excess of oxygen for the release of heat and light (energy) is known as combustion.

Following are some of the examples of the combustion reaction of organic compounds:

C + O2 ⇨ CO2 + Heat + Light

C3H8 + 5O2 = 3CO2 + 4H2O.+ Heat + Light

(C3H8 is the molecular formula for Propane, a common gas present in LPG which we burn for cooking in our kitchens).

In General, saturated hydrocarbons burn with a clear blue flame, whereas unsaturated hydrocarbons burn with a yellow flame producing soot (carbon).

Combustion of hydrocarbons may be of two types: Complete combustion and incomplete combustion.

Complete combustion of hydrocarbons occurs in excess of oxygen(air), producing CO2 and H2O as the only final chemical products.Heat and light (clear blue flame) as a form of energy is generated.

Answer 2

Explanation:

compaction : when carbon compound burn in oxygen to give CO2 and water vapour heat and light also released during this reaction the reaction is called combustion

substitutional reaction : reaction in which reagent replace and atom or group of atom from reactants are called substitutional reaction

1. combustion reaction with taking example of Methane : CH4+2O2 ---- CO2 +2H2O + Heat &light
2. substitution reaction with taking example of Methane : CH4 --- CH3Cl
