Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules reacting during chemical changes

Melting Point and Boiling Point of Organic Compounds Bongo‚ Sayre‚ J1 1Student‚ Organic Chemistry 1 Laboratory / B11‚ School of Chemical Engineering‚ Chemistry and Biotechnology‚ Mapúa Institute of Technology ABSTRACT The melting point of a substance is the temperature at which the material changes from a solid to a liquid state while the boiling point is the temperature at which it changes from liquid to solid. In this experiment‚ the main objectives were to determine the effects of the following

Organic vs. Inorganic Le’Trice Crawford CRJ311: Forensics Christopher Mancuso May 18 ‚ 2012 The world that we live in is made up of organic and inorganic materials. The thing is known which is when you are confronted with a list of objects. This is the reason in this paper I intend to show the difference between organic and inorganic organisms. The definition of organic which means‚ of or pertaining to an organ; or the organs of an animal

A chemical reaction is a process in which the identity of at least one substance changes. A chemical equation represents the total chemical change that occurs in a chemical reaction using symbols and chemical formulas for the substances involved. Reactants are the substances that are changed and products are the substances that are

in the understanding of chemical properties‚ and culminates with the publication of the first actual periodic table by Dmitri Mendeleev in 1869.[1] While Mendeleev built upon earlier discoveries by such scientists as Antoine-Laurent de Lavoisier and Stanislao Cannizzaro‚ the Russian scientist is generally given sole credit for development of the actualperiodic table itself. The table itself is a visual representation of the periodic law which states that certain properties of elements repeat periodically when

Year 11 Module 1 – The Chemical Earth The Earth is made up of a large number of different substances: elements‚ compounds & mixtures We can classify elements & compounds as pure substances. These are always HOMOGENEOUS. Mixtures are not pure substances and can be either homogeneous or HETEROGENEOUS. Pure substances have a fixed composition eg copper metal‚ sulfur‚ carbon dioxide (CO2)‚ methane (CH4). Mixtures have variable composition and can also be separated into its components relatively
