CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances‚ it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive‚ or independent

IB Interesting Facts 1968‚ IB‚ standing for the International Baccalaureate‚ has been founded as a non-profit educational organization at the International School of Geneva. It was created by teachers at the school‚ in addition to help from teachers from all over the world. Today‚ the International Baccalaureate has grown into a university preparatory program that has been divided‚ in most schools‚ into three programs for students as young as 3 years old to students 19 years old. • It was first

computer ------------------------------------------------- Computational chemistry From Wikipedia‚ the free encyclopedia Computational chemistry is a branch of chemistry that uses principles of computer science to assist in solving chemical problems. It uses the results of theoretical chemistry‚ incorporated into efficient computer programs‚ to calculate the structures and properties of molecules and solids. Its necessity arises from the well-known fact that apart from relatively recent results

The lab was to include a purpose‚ procedure‚ data/observations‚ all reactions and side reactions written out with qualitative data beneath each product and reactant except H20‚ and a summary. The purpose of this experiment is to observe the qualitative aspects of a series of reactions involving copper. Procedure 1.Measure about 1g of solid copper. 2.Place Cu in Erlenmeyer flask and place flask under fume hood. 3.Add dropwise 15M HNO3 until solid copper is completely reacted. 4.Place flask

reactants are separated. A chemical change is when the reaction changes the reactants and creates a brand new substances that can’t be reversed. Antoine Lavoisier had the main contribution to The Law of Conservation. He wrote a textbook in 1789 on chemistry in it he introduced the Law of Conservation. He founded the 3 types of matter (solid‚ liquid‚ and gas). Along with this he also established the metric system. Lavoisier also made a lot of enemies because he had disproved various old theories.
