function that keeps living organisms alive. Another living property that living organisms possess is regulation. The environment outside of an organism may change drastically. However living organisms can adapt to such drastic changes by adjusting its internal environment therefore being able to coordinate internal functions, respond to stimuli, and cope with environmental stresses. All organisms grow and develop; another very important property that characterizes living things. Information carried by
* Chemistry Laboratory Report * * * Aim * * To Methodically identify ten different compounds by performing a series of tests on ten unknown white solids. * * * Introduction * * The series of tests known as an analytical scheme, should allow the compounds to be identified in an efficient manner. * * The ability to scientifically identify unknown substances offers a variety of important capabilities. For example, the ability to ascertain whether
What is the difference between a compound and a mixture? Answer: A compound is a substance in which atoms of different elements are chemically held to one another. A mixture is a substance made by combining two or more different materials in such a way that no chemical reaction occurs. A mixture can usually be separated back into its original components, a compound cannot. Compounds * Compounds are pure substances. * They are made up of two or more elements combined chemically.
involving the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of carbon-based compounds, hydrocarbons, and their derivatives. These compounds may contain any number of other elements, including hydrogen, nitrogen, oxygen, the halogens as well as phosphorus, silicon, and sulfur. Organic compounds are structurally diverse. The range of application of organic compounds is enormous. They either form the basis of, or are

the structure and properties of matter. Why is Chemistry Important? Almost all foods, beverages, and cleaning products have chemical compounds in them to preserve freshness or remove dirt. Substance Substances – matter that has a uniform and define composition; either an element or a compound. What about Molecules A molecule is formed when two or more atoms join together chemically. A compound is a molecule that contains at least two different elements. All compounds are molecules, but
Although most elements are found in combinations on Earth, some elements are found uncombined 5 3. Elements in Earth materials are present mostly as compounds because of interactions at the atomic level 5 4. Energy is required to extract elements from their naturally occurring sources 7 5. The properties of elements and compounds are determined by their bonding structure 8 Skills Summary/Outline 10 1. The Chemical Earth The living and non-living components of the Earth
6, 2013 Section Assessment on page 42 (#’s 1–4) and (#’s 5 and 7) 1. Name two categories used to classify properties of matter. Two categories used to classify properties of matter are extensive and intensive. 2. Explain why all samples of a given substance have the same intensive properties. All samples of a given substance have the same intensive properties because every sample has the same composition. 3. Name three states of matter. Three states of matter are
naked eye and its physical and chemical properties. Also, it studies the changes that happen to the matter due to their reactions and the energy that come out of the reaction. In addition, it studies the types of matter's reactions such as combustion, decomposition and dissociation. Although chemistry is an earliest science, it still discovering more information that explains a lot of phenomenon. Chemistry is divided into different branches due to their properties. Chemistry has a lot of branches; the
INTRODUCTION Hydrocarbons are organic compounds that contain only carbon atoms and hydrogen atoms. Examples of hydrocarbons include fossil fuels, such as gasoline and natural gas. Hydrocarbon from which one Hydrogen atom has been removed are functional groups called Carbonyls. The majority of hydrocarbons found on earth naturally occur in crude oil where decomposed organic matter provides an abundance of carbon and hydrogen which, when bonded can catenate to form seemingly limitless chains.
