Plastics or Not?


Plastics

By: Areta




To start of plastic is a “synthetic organic polymer” ( Anne Marie Helmenstine, ThoughtCo.) Meaning their chemical composition is made up of carbon and hydrogen. Plastics are made out of polymers, though polymers have a chemical structure of that include carbon and hydrogen, there are able to add other molecule structures to make different types of plastics. Polymers are unsaturated, meaning during fabrication other bonds can be added and break the double bond, making it complete. These added molecules, structures, can be known for colorants, stabilizers, fillers, and reinforcements. These additives can affect the physical structure, chemical, and usage as well as cost. Examples of different plastics, their chemical formulas, and their use include;

High-density polyethylene—HDPE: (HDPE was first produced in England and became famous in the 1950s in the united states. It makes a by a chain of ethylene molecules. The properties of HDPE include: it is light and super strong. It is used to make products such as a milk gallon container. It is long lasting as well as malleable. Meaning it is flexible.

Polypropylene—PP (Propopleye is a polymer that is made up of, propylene molecules (monomer).  Propylene is used for various purposes around the world today, which include packaging for products, and plastic for industries. Propylene has a high resistance towards room temperature, and organic solvents ( fats). Though propylene does not support heavy weight or like doors, and desks. It is useful for products for ketchup caps, bottle caps etc.

Polystyrene—PS:  Polystyrene is a chain of styrene molecules. It is inexpensive and hard. The outside part of a   chrome computer is made of polystyrene, as well as model cars, Styrofoam cups, radio knobs.

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...
