time. After they are detected, a chromatogram is generated. Each peak in a chromatogram represents a different component of the original mixture. Time can be used to identify and peak size for detection the amount. Compounds that are mixed together are separated by GC and the chemicals are fragmented into a unique spectrum by MS. A sample is dissolved into a specific liquid which is then injected into a stream of gas. Generally used gases are nitrogen or hydrogen. Then the gas containing the…

are used with Oxygen will have the word “ate” in them. Nitrate is an example of a Polyatomic Ion. Polyatomic Ions are referred to as a radical, and less commonly, as a radical group. There are many differences between a polyatomic ion and a compound. Polyatomic ions are composed of two or more atoms that are linked to covalent bonds. Yet, they still have a net deficiency or surplus of electrons, resulting in an overall charge on the group. Polyatomic ions are created when a number of…

benefit from bonding of atoms of certain elements in our daily life. As I will show in this essay, with the help of understanding the surface chemistry, which is the study of chemical reactions at interfaces (surfaces), different desired affects can be produced by the formation of selected elements such as making improved chemical composition of a surface. Surface chemistry today can be applied to solve various issues and problems including fighting corrosion, making glucose biosensor to…

Stoichiometry is known as the quantitative relationship between various products and reactants in a chemical reaction. There are many ways one can stoichiometry in his/her advantage. If you start off with a known amount of reactant, stoichiometry can definitely be used to make a prediction to the amounts of the future product that will be formed. And in the other side, if you has a desired amount of product want, you can use stoichiometry to predict of on how much reactant you will need to…

Introduction: Chemical bonding can be formed by joining two or more atoms together. Throughout the lab various experiments were tested to form a chemical bond. Most people can tell the difference between the two main forms of chemical bonding ionic and covalent. With each bond that comes with a reaction. There were four types of chemical reactions that were mentioned in class. They are as follows Synthesis, Decomposition, Single Replacement, and Double Replacement. Synthesis is one of the more…

terpene that can be isolated from orange peels almost 100% in the (R)-(+)-limonene form. The essential oil from the orange peel belongs to terpenes, which are compounds that are made up of two or more five carbon units, named isoprene.1 The limonene is a monoterpene, which means it is made up of two isoprene units. Natural products are related compounds formally derived from isoprene units are terpenoids.3 The skeleton of terpenoids may differ from strict additivity of isoprene units by the loss…

atmosphere. This reaction is known as a single displacement reaction because aluminum switches with the hydrogen. When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al + 6HCl = 2AlCl3+ 3H2. The reaction produces two moles of aluminum chloride and three moles of hydrogen gas. The aluminum donates its valence electrons to become aluminum chloride During this reaction…

1. Distinguish between a chemical change and a physical change. Illustrate each using several examples. A physical change does not change the substance of the matter the identity does not change. A chemical change produces a new substance and absorbs or liberated heat. Chemical changes produce an indication of chemical change substances combine chemically producing new substances that cannot separated by physical means. Examples of physical changes: Dissolving salt in water is a physical…

a priority when conducting labs. Especially when handling chemicals, the ideal setup of labs should avoid any obstructions and potential hazards that may occur. This is due to the possible dangers: flammable and combustible chemicals (alcohol, sodium), oxidation (hair dye), bio hazardous products (which causes AIDS, rabies), toxic items (lead, benzene), poison (carbon monoxide), corrosive compounds (bleach), dangerously reactive chemicals (fluorine) and compressed gas (propane, CO2). Regarding…

This essay will be talking about Reactions and how it affects substances.A reaction is a chemical process in which two or more substances act on each other and are changed into different substances, or one substance changes into other substances.There are eight reactions we will be talking about and they are Decomposition,Combustion,Acid and Base,Synthesis,Single-replacement,Double-replacement,Precipitation,and Redox.In the world today there are many reactions out their but we will only be…
