distillation and gas chromatography based on their difference in boiling points. The boiling point of hexane is 69 degrees Celsius and the boiling point of toluene is 110 degrees Celsius. Three fractions were collected for both simple and fractional distillation. The first fraction was hexane since it had the lower boiling point. The second fraction was a mixture of toluene and hexane. The third fraction was toluene since it had the high boiling point of 110 degrees Celsius. Gas chromatography was

________ Page 1 Name ______________________ Evaluation of the Gas Law Constant Objectives In this experiment‚ we will determine the Ideal Gas Constant‚ R‚ which relates the number of moles of gas present to its volume‚ pressure and absolute temperature. Background To see how "R" was derived‚ we must look at the proportionalities defined by the other fundamental gas laws. For example‚ Charles’ Law showed us that the volume of a gas sample is proportional to its absolute temperature at constant pressure

It is traditional to divide industries into categories according to the degree of competition that exists between the firms within the industry. There are four such categories. At one extreme is perfect competition‚ where there are very many firms competing. Each firm is so small relative to the whole industry that it has no power to influence price. It is a price taker. At the other extreme is monopoly‚ where there is just one firm in the industry‚ and hence no competition from within the industry

Making and Testing for Hydrogen Gas Felicity Tyler Aim: To produce and test for hydrogen gas. Materials: * rubber stopper * dilute hydrochloric acid (HCI) * zinc pieces (Zn) * test-tube rack * matches * dilute sulphuric acid (H2SO4) * 2 cm strips of magnesium ribbon (Mg) * Iron pieces (Fe) * Test-tube Method 1. Test the different metals with the acids by separately combining

involving a metal and relate this to an understanding of the mole. METALS Reacting Gas Volumes AIM: to investigate the relationship between the volumes of gases involved in a reaction. HYPOTHESIS: A new gas will form when two gases will react together. BACKGROUND INFORMATION: Nitric oxide and oxygen are both colourless gases which do not dissolve in water. However‚ when they mix they form a different gas called nitrogen dioxide which is brown‚ soluble in water and has a particular odour

Blaise Pascal (1623-1662) France Pascal was an outstanding genius who studied geometry as a child. At the age of sixteen he stated and proved Pascal’s Theorem‚ a fact relating any six points on any conic section. The Theorem is sometimes called the "Cat’s Cradle" or the "Mystic Hexagram." Pascal followed up this result by showing that each of Apollonius’ famous theorems about conic sections was a corollary of the Mystic Hexagram; along with Gérard Desargues (1591-1661)‚ he was a key pioneer

OUtLINING It might prove useful to organize the ideas that suggest themselves during the freewriting and clustering exercises into a preliminary outline form. It is possible to write a paper without an outline‚ but it might suggest that your paper lacks organization if it proves impossible to write an outline that describes the thinking process behind your paper. Outlining never hurt; how helpful it is depends on what kind of thinker you are. At the least‚ a tentative outline can suggest areas in

Loving a person isn’t about logic or reason. (Paradise Kiss) Is there a limit to how much you can love somebody? No matter how much I hurt him or get hurt by him‚ I find myself far from hating him‚ actually hoping that those wounds will scar‚ like burns…because then you can never forget me. Kamijou Hiroki (Junjou Romantica) Everyone goes around trying to find their soulmate‚ but no matter how hard they look‚ they can never find it. So instead‚ they force two bodies together.

Also it could be defined as a two liquid are ideal solution when they don’t react with each other and they make no association. 2) Are a mixture of at least two different liquid‚ and known also as a mixture of two or more liquid in such away that its component
