Combustion is a chemical reaction in which a fuel is burnt in the presence of oxygen to form carbon dioxide, water and heat. Thus the chemical energy stored in the bonds of reactants is converted to thermal energy and heat is released in the combustion reaction.

• Burning of Wood or Coal for the household purposes.
• Burning of Petrol or Diesel for using vehicles like car.
• Combustion of Natural Gas or LPG to cook.
• For the production of energy in thermal power plants.
• Fireworks.

Answer: Combustion is a process of burning a substance in the presence of air or oxygen, as a result of which heat and light are produced.

Three things are required in proper combination before ignition and combustion can take place—Heat, Oxygen and Fuel. There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.

A combustion reaction occurs when a substance reacts quickly with oxygen (O2). For example, in the Figure below, charcoal is combining with oxygen. The products of a complete combustion reaction include carbon dioxide (CO2) and water vapor (H2O). The reaction typically gives off heat and light as well.

Combustion is a chemical process or a reaction between Fuel (Hydrocarbon) and Oxygen. When fuel and oxygen react it releases the heat and light energy. Heat and light energy then result in the flame. So, the formula for Combustion reaction is Hydrobcarbon + Oxygen = Heat energy.

Therefore the quantity of oxygen required for combustion of 1 kg of the fuel is: (2.66C + 8H + S) kg. ∴ Oxygen required from air for the complete combustion of fuel will be (2.66C + 8H + S – O) which can be written as 2.66C + 8 (H – O/8) + S, the term in the bracket being known as the available hydrogen.

The energy that the reaction produces can be used to heat water, cook food, generate electricity or even power vehicles. The products of combustion reactions are compounds of oxygen, called oxides.

1 Answer. The basic difference is that combustion is heating and no flames are produced whereas in burning most of the energy is converted to light energy and this results in less heat energy as compared to combustion.

Oxygen. Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, etc.).

Rapid combustion: Rapid combustion is a form of combustion in which large amounts of heat and light energy are released. Example: Matchstick burns rapidly on being struck against the sides of a matchbox. Combustion of natural gas, LPG, petrol etc.

Fire is the visible effect of the process of combustion – a special type of chemical reaction. Combustion is when fuel reacts with oxygen to release heat energy. Combustion can be slow or fast depending on the amount of oxygen available. Combustion that results in a flame is very fast and is called burning.

In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen.

To summarize, for combustion to occur three things must be present: a fuel to be burned, a source of oxygen, and a source of heat. As a result of combustion, exhausts are created and heat is released.

Combustion (burning) by-products are gases and small particles. Examples of combustion by-products include: particulate matter, carbon monoxide, nitrogen dioxide, carbon dioxide, sulphur dioxide, water vapor and hydrocarbons.

Products of Combustion

• Carbon Dioxide.
• Carbon Monoxide.
• Sulfur Dioxide.
• Nitrogen Oxides.
• Lead.
• Particulate Matter.

The products of a complete combustion reaction include carbon dioxide (CO2) and water vapor (H2O). The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is: Fuel + O2 → CO2 + H2O.

Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. …

Good signs that you’re dealing with a combustion reaction include the presence of oxygen as a reactant and carbon dioxide, water, and heat as products. Inorganic combustion reactions might not form all of those products but remain recognizable by the reaction of oxygen.

Combustion is the complete oxidation of organic compound into carbon dioxide and water molecules in presence of oxygen gas whereas oxidation is the addition of oxygen in a compound or addition with an element. Combustion reactions involve heat and light whereas oxidation reaction does not involve heat.

Fire is burning, which is combustion, and combustion is a type of oxidation reaction. Oxidation means combined chemically with oxygen . Oxidation is an exothermic reaction, meaning it gives releases heat energy.

Combustion is a rapid process while rusting is a slow process. 2. Combustion releases light during the process while rusting does not produce any light. Combustion results in release of large amount of heat while rusting very little amount of heat evolved.

Oxidation is defined as a process in which an electron is removed from a molecule during a chemical reaction. What happens in oxidation? During oxidation, there is a transfer of electrons. In other words, during oxidation, there is a loss of electrons.
