Combustion


Definition: rapid chemical combination of a substance with oxygen, involving the production of heat and light.
Combustion is an exothermic reaction because it releases energy through light or heat.
The product of combustion reaction is heat.
It is a type of redox reaction.
what is a Redox reaction? Oxidation reduction or redox reaction is a type of chemical reaction in which the oxidation number of  molecule, atom, or ion changes by gaining or losing an electron.
Examples of combustion reactions include:
"2 H2 + O2 → 2H2O + heat
CH4 + 2 O2 → CO2 + 2 H2O + heat"

A few real life examples of combustion could be: 
  1. BBQ's
  2. Gas ovens
  3. Forest fires
  4. Bonfires
So this is applicable to our life because sometimes we use combustion to our benefit for example"BBQ's" and "Bonfires".

Combustion Reaction🔥

                                                                                  Reactions Complete Versus Incomplete Combustion  So there is something we call a complete combustion and the other a dirty combustion. Fuel such as petrol or methane, etc can undergo complete or incomplete combustion. When methane completes a complete combustion it produces carbon dioxide and water. When methane goes through an incomplete under a limited amount of air it produces carbon monoxide and water or carbon or water. What is Combustion? There are many types of combustion. But I believe the most known one is the combustion with methane which is the one I put above.  Combustion can also be called burning. Combustion is an exothermic reaction which means it gives out heat. Re...

Isomerization

Research: What are structural Isomers? Online definition:  In chemistry isomerization is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms have a different arrangement My definition: When the arrangement of a molecule is changed but still has all of the same atoms. (Alkanes) Examples : - Methane - Ethane - Propane  - Butane VIDEO: Constitutional Isomers : Isomers that differ in connectivity Simple hydrocarbons such as; methane, ethane, and propane can not have constitutional isomers because there is no other way to connect them.   There are 2 different butanes that re constitutional isomers. CITATIONS: “What Is Isomerization? - Definition from Petropedia.” Petropedia.com , www.petropedia.com/definition/7019/isomerization. “Isomerization.” Wikipedia , Wikimedia Foundation, 23 Sept. 2018, en.wikipedia.org/wiki/Isomerization.

Melting Point of Different Plastics

For my lab, I will be testing the melting points of different plastics. My Independent Variable will be the different plastics My Dependent Variable will be the melting point of different plastics My Control Variable will be the amount of plastic I will be putting into the oven to melt. To determine the melting point, I have to be observing the plastic for the whole time while it is being heated. I have to be observing very closely because, to determine the melting point I have to see when the plastic starts to melt and when it is completely melted (1). I will be using two plastics two compare each other, I will use Polyethylene terephthalate which is the most produced plastic in the world and Polyethylene, these two plastics are the most common plastics (2). I will be comparing the melting point of each of the plastics and finding out what plastic is more resistant to heat. Polyethylene terephthalate is thermoplastic which means that it reacts to heat in a ...
