ABSTRACT Determining the melting point of a solid organic compound is the easiest way to identify the compound and determine its purity at the same time. For actual samples of compounds‚ the melting will occur over a range of temperatures making the melting points into a melting “range”. The difference between the temperature at which the sample begins to melt and the temperature at which it finishes melting‚ or the magnitude of the melting range‚ is a very important criteria of determining the

Using Freezing-Point Depression to Find Molecular Weight Abstract: In this lab‚ the purpose was to use the freezing point depression method to determine the molecular weight of aspirin. This was done by determining the freezing of t-butanol and that of a t-butanol and aspirin solution; then finding the molality of the solution‚ and moles of aspirin. In the results of the experiment‚ the molar mass was found to be 192.2 g/mol‚ which differed from the established value of 180.2 g/mol by 6.7% error

Repressed ethnic and national groups around the world heard Wilson’s call for "national self-determination" as the herald’s trumpet for a new era as the 14 Points list the foundation for world peace. Despite their introduction after World War I in 1918‚ the 14 points are still relevant today as these ideas establish peaceful ideologies in other countries worldwide to maintain their people.

Wilson’s most famous speech. The speech had fourteen main points thus the speech became known as Wilson’s fourteen points. The speech states what Wilson felt was essential to establish peace. The purpose of the speech was to establish moral rules between the participants of WWI. Of the fourteen points talked about eight concerned specific geopolitical issues. The remaining six were basic ideas necessary for peace. The most important of these points were freedom of the seas‚ an end to secret treaties and

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
