Single Displacement Reaction

Single Displacement Reaction
A single displacement reaction is when an element reacts with a compound and in the product, takes then the place of another element in that compound (Studer, 2018). That is why sometimes it’s also known as a single replacement reaction.


This website has a video of how a single displacement reaction works:
The reaction that will be shown in this blog will be between potassium (K) and water (H2O). the elements in this reaction will be potassium, hydrogen, and oxygen.
2K + 2H2O → 2KOH + H2
As shown in the reaction, potassium starts as a single element and water is a compound molecule. After the reaction takes place potassium has replaced a bit of hydrogen and bonded to an oxygen-hydrogen compound.
Potassium is a metal and reacts with water rapidly to create a colorless solution that ends up being potassium hydroxide (“webelements, 2018).
This reaction is exothermic. At the beginning of the reaction, potassium becomes very hot and even catches fire that causes the element to have a lilac purple-like color.
Potassium and water are used in everyday life however this reaction does not. Water is used to keep us hydrated and alive as well as other daily functions such as hygienic needs. Potassium, in small amounts is also important for the body because it conducts electricity and helps the heart, digestive track, and muscle to function (Gannett, 2017).

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.

Welcom to AmSkul Science 2018-19!!

Welcome! This is a blog for my science students to post their research, their projects, their interesting findings. We want to try to collaborate with the greater scientific community and share some of what we have found on topics we cover in class. Happy to have you here with us! Feel free to comment and add questions so we can continue to collaborate and come to a greater understanding of the world together. -Ms. Maiya

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...
