Molecule Research Paper- Propylene Glycol 1, 2-Propanediol, also known as Propylene Glycol, is an organic compound used in a variety of skin care products. In these paragraphs, you will read about the overall structure of the molecule, the most common uses for the molecule, the physical properties that the molecule is comprised of, and an important news article that shocked the nation regarding the molecule. The chemical formula of Propylene Glycol is C3H8O2. It contains, as the chemical formula shows, three Carbon atoms, eight Hydrogen atoms, and two Oxygen atoms. If a lewis dot diagram is drawn out (as seen on the picture below, to the right), it can be seen that there are only single bonds throughout the entire molecule, and well as only two lone pairs. As depicted in the picture below to the left, the geometric shapes that make up the molecule are two bent and three tetrahedral shapes.

In its appearance, it seems to be similar to water- it is colorless and odorless. However, it is considerably more thick and viscous than water, and it is documented to have a slightly sweet taste. The molecule is both polar and containing hydrogen bonds. Due to the fact that it is polar, and like-dissolves-like, propylene glycol is indeed soluble in water, and is often sold this way in smoke machine liquids. Its ability to be soluble in water and to disrupt ice formation is also what makes it an ideal antifreeze chemical. It is not a highly reactant chemical, and is fairly stable and safe- another reason it is marketed so often. If it gets exposed to very high temperatures, however, it may become flammable. It decomposes in a fairly short amount of time- if it is in the air it can take 24-50 hours, and elsewhere, it takes anywhere from couple days to a week to break

    The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation, the process in which a cell takes up and expresses a new piece of genetic information, the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their tools, and other supplies for as long as they need, and keep them from touching anything. They must also learn that tools can never be shared between specimens, and when they use a tool, they should dispose of it and get a new one. Next they need to learn how to transfer a bacterial colony. To do this, one must use a sterile loop and scrape one colony off of the dish. Then they must insert the loop into…

    According to Lee Lerner, (2008), “Hydrogen Peroxide is most widely found in homes in brown bottles containing three percent solutions (3% hydrogen peroxide and 97% water).” Lee Lerner (2008) writes “Hydrogen Peroxide is a colorless liquid that mixes with water and is widely used as a disinfectant and bleaching agent.” Hydrogen Peroxide is used in many different ways and has different hazards. “Hydrogen peroxide is a strong oxidizing agent used in aqueous solution as a ripening agent, bleach, and topical anti-infective.” (“Hydrogen” 2004). “Hydrogen peroxide is clear, colorless, water like in appearance, and has a characteristic pungent odor. Nonflammable, it…
