form larger molecules known as polymers. In doing so‚ monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis. In a dehydration synthesis reaction‚ the hydrogen of one monomer combines with the hydroxyl group of another monomer‚ releasing a molecule of water. At the same time‚ the monomers share electrons and form covalent bonds. As additional monomers join‚ this chain of repeating monomers forms a polymer. Polymers are broken down into monomers in

A candle is a solid block of wax with an embedded wick‚ which is lit to provide light‚ and sometimes heat‚ and historically as a method of keeping time. A candle manufacturer is traditionally known as a chandler.[1] Various devices have been invented to hold candles‚ from simple tabletop candle holders‚ to elaborate chandeliers.[2] For a candle to burn‚ a heat source‚ commonly a naked flame is used to light the candles wick which melts and vaporizes a small amount of fuel‚ the wax. Once vaporized

A protein is a Biological polymer made up of as different amino acids joined by peptide bonds. A protein is formed by amino acids which are the basic building block of a protein components of an amino acid include a :C-carbon atom‚ H-Hydrogen atom‚ H3N+ - Amino Group‚ COOH- - Carboxyl Group‚ R- this group varies from amino acid to amino acid. There are 20 amino acids‚ each differing in its R group. Two examples are: Glycine‚ its R group being H(Hydrogen) and Phenylalanine its R group being CH2 (Carbon

We make the decision of what we are going to eat and how the foods will take effect on our body. The purpose of this essay is to compare and contrast the differences between eating homemade meals instead of fast food meals. The three main differences are health benefits‚ the cost‚ and less

Effect of Temperature on Polymers: Solids on heating eventually melt to form a liquid. With polymers it is not so simple rubber on cooling (in liquid nitrogen) becomes brittle or glassy. Many polymers have a mixture of ordered (crystalline) regions and random (amorphous) regions. In the glassy state‚ the tangled chains in the amorphous region are frozen so movement of chains is not possible the polymer is brittle. If the glassy material is heated‚ the chains reach a temperature at which they

#4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles are

One reason often heard from people using drugs is that they do them to feel good. For real‚ it does feel good because most drugs act directly on the "pleasure center"--the limbic system--in the brain . At this point‚ it can be considered recreational use. Some might light up a cigarette at a party. They might not consider themselves a "smoker‚" but they do it to feel good or to "look cool." Someone might smoke pot at their friend’s house because they think it could be fun. The problem? Drugs don’t

CHAPTER III MATERIALS AND METHODS This research study used the process of extraction to test the effectiveness of Acapulco (Cassia Alata) leaves in killing or eradicating the fungi Microsporum canis. The raw material that the researchers used in the experiment is the Acapulco with the scientific name Cassia Alata. It belongs to the family of Leguminosae. It is a shrub which is erected and grew for about 2 meters tall. The leaves of the plant posseses fungicidal‚ insecticidal and pesticidal

In “A Homemade Education”‚ by Malcolm X‚ the intended audience is any individual‚ primarily from the minority groups. Malcolm X states that how is one to “get civil rights before first he wins his human rights (X 233)?” This pieces main purpose is to persuade the reader to dive in a mind set of an “Austrian monk (X 230).” An individual who can apply his understanding in reality‚ with hopes of acquiring piece and prosperity. Being locked in prison was his best bet‚ as an “articulate hustler (X 227)”
