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).

What are covalent bonds and why are they important

                              Covalent bonds A covalent bond also known as molecular bound is when two nonmetals share electrons. The bonding starts forms when the electrostatic attraction of their nuclei are aiming for the same electrons. Atoms will share electrons with other atoms to be stable,  stability is gained by filling their electron shell, and each shell except for the first one needs 8 electrons to have a full shell. For example, Co2, carbon bonds covalently with 2 oxygen to have a full outer shell, oxygen needs 2 electrons to have a full outer shell and carbon, and carbon needs 4 more electrons for a full outer shell, so its going to bond with the oxygen and both elements will be stable. Due to the sharing of electrons, they show physical properties  that include lower melting points and lower  electrical conductivity  compared to ionic compounds .  There are two ...

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 H 2  + O 2  → 2H 2 O + heat CH 4  + 2 O 2  → CO 2  + 2 H 2 O + heat" ( https://chem.libretexts.org/Textbook_Maps/Analytical_Chemistry/Supplemental_Modules_(Analytical_Chemistry)/Electrochemistry/Redox_Chemistry/Oxidation-Reduction_Reactions ) A few real life examples of combustion could be:  BBQ's Gas ovens Forest fires Bonfires So this is applicable to our life because sometimes we use combustion to our be...

Chemical Reactions

Chemical Reaction A chemical reaction is an action that leads to the transformation of one set of chemical substances to another. A well known chemical reaction is when mixing ethanoic acid with sodium hydrogen carbonate. Chemically the ethanoic acid reacts with the sodium hydrogen carbonate to form carbon dioxide gas and water. The carbon dioxide gas produced rushes away from the water. This is seen as bubbles.This is a double replacement reaction and the sodium ion reacts with the acetate ion. Giving Sodium Acetate And a H+ Ion reacts with the bicarbonate ion giving carbonic acid which decomposes into water and carbon dioxide. This reaction happened because of a substance called entropy. Entropy is a property of matter that can quantized by randomness of disorder. An example will be how a solid has a lower entropy than liquids and gasses due to the fact that molecules of gases have an increase freedom of movement. Entropy is one part...
