Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be compared.

In order to successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical yield of .102 g equaled an overall 75% percentage yield. Considering the product yield was only a quarter shy of a 100% yield

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

HOW TO FIND OUT POINT GROUP Dr. Cyriac Mathew Symmetry elements can combine in a definite number of ways. For example consider BF3 molecule. It has the C3 axis as the principal axis. Also‚ there are 3 C2 axes perpendicular to the C3 axis‚ 3 σv planes‚ and one σh plane. All these symmetry elements can combine. Take NH3. It also has C3 axis as principal axis. There are 3 σv planes‚ but no C2 perpendicular to C3 or a σh plane. For the N2F2 molecule there exist one C2 axis and a σh plane but
