Combustion Essay. Burning, otherwise known as combustion, is an important chemical reaction.

Extracts from this document...

Introduction

Cheryl Chan 8YC/8C Science/Mr. Lee Are chemical reactions important? Burning, otherwise known as combustion, is an important chemical reaction. It is the state, process, sensation, or effect of being on fire, burned, or subjected to intense heat. The act of combustion often results in a fire, which contributes greatly to the world as it gives out energy and light. There are six different types of burning: rapid, slow, complete, incomplete, turbulent and microgravity. Combustion is made according to the following formula: Fuel + Oxygen ? Carbon Dioxide + Water + Energy/Burning. It is a complex chemical sequence of exothermic reactions, in which a substance reacts rapidly with oxygen and gives off heat. Combustion is made when a fuel burns in oxygen, accompanied by heat or both heat and light. The original substance, the fuel, can be a solid, liquid, or gas and the source of oxygen; the oxidizer could also be a solid, liquid, or gas. New substances called oxides or exhaust are made as the fuel burns and come from chemical combinations of the fuel and oxygen. ...read more.

CO + 2H20 +Energy. Methane originally is CH4 and most of the molecules in the above equation are in a gaseous form. One molecule of methane combined with two oxygen molecules react to form a carbon dioxide molecule, and two water molecules usually given off as steam or water vapor during the reaction and energy. The chemical reaction of burning is important to the world because basically, it makes fire. Fire is a tool for cooking, defense, and security, a survival tool. It gives warmth and light. When you unharness it, it can bring destruction and aids in wars and battles. Combustion fulfills the important role on Earth of being the source of fire, as said before; and it enables human beings to keep warm, cook or just to survive. Also, burning is one of the sources when producing energy like electricity. The world and our lives would be very different if we did not have this chemical reaction. ...read more.

Conclusion

Some of the nutrients are lost to the atmosphere as smoke but combustion also releases many nutrients into the soil. This "flush" of nutrients is then available to plants that re-establish in burnt areas. This function of fire is useful to country parks where the rates of decomposition and nutrient cycling are low. However, burning needs to occur in forests and country parks before being able to help the forest soil. Forest fires, the creation of combustion, wipe out many trees in the process of burning. Therefore, the trees: homes to animals, creators of oxygen and takers of carbon dioxide, are lost. Also, the act of combustion contributes to global warming by producing smoke and greenhouse gases, especially when burning a large amount of fuel. The act of burning is probably one of the most important chemical reactions in the world. Although it can bring severe damage to both the environment and human beings, it benefits everyone at the same time by giving energy. Therefore, burning is a good example of a chemical reaction which is important in the real world. ...read more.
