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 ...

Precipitation

Precipitation Precipitation is any forms of particles, whether liquid or solid, that Precipitation reaction leads to a reaction  that leads to the formation of a heavier solid in a lighter liquid. Precipitation is basically any product of the condensation of the atmospheric water vapor that falls under gravity. This occurs when a portion of atmosphere becomes saturated with water vapor. There are two processes, possibly acting together, can lead to the air and it becomes saturated. Cooling the air or adding water vapor to the air. Precipitation  forms as smaller droplets coalesion with other rain drops or ice crystals within a cloud. Short periods of rain  in scattered location are named showers. An example: Mixing silver nitrate and sodium chloride in water will cause silver chloride to precipitate out of   solution   as a   solid . In this example, the precipitate is silver chloride. When writing a chemical reaction, the presence of a precip...

Displacement reaction

A chemical reaction is when one or more substances which are reactants are changes into one or more different substances which then becomes the product.  A chemical reaction is written with the formula of reactants on the left side, and formula of the products formed on the right. An arrow is placed in-between the reactants and the products. They are 5 types of chemical reaction; Synthesis reaction/combination Decomposition Reaction Displacement or Replacement Reaction Acid Base Reactions Combustion Reaction I'll be explaining one of these five reaction which will be  Single displacement reaction .  Single displacement reaction is part of the reaction "Displacement or Replacement Reaction. Single displacement reaction happen when a cation(positive) and an anion(negative) swap from a compound.  The general formula for a  single replacement reaction  is A + B-C → B + A-C where  A  is an element and where  B-C  is a c...
