Extraction of R’-NH2 For both of the organic acid and organic base extraction‚ the addition of the respective inorganic acid or inorganic base (HCl or NaOH) to the three-component mixture caused an immiscible appearance of the solution in the separatory funnel. By briskly shaking the separatory funnel with the mixed components created a build up of pressure which was released through the stopcock forming small disappearing bubbles within the tip of the separatory funnel. Once the funnel was placed

Clockwork Orange has been called shocking‚ controversial‚ and horrifying. A Clockwork Orange is controversial‚ but to focus merely on the physical aspects of the work is time wasted. Burgess is concerned with the issue of ethics. He believes that goodness comes directly from choice; it is better to choose the bad than to be forced into doing the good. For taking away a person ’s free will is simply turning them into a piece of "clockwork"; a piece of machine containing all the sweet juices of life

Anna Powell 2nd I.Title: Acid-Base Titrations AP Chemistry Laboratory #6 II.Purpose: The purpose of this experiment is to standardize a sodium hydroxide solution and use the standard solution to titrate an unknown solid acid. The equivalent mass of the solid acid will be determined from the volume of sodium hydroxide added at the equivalence point. The equilibrium constant‚ Ks‚ of the solid acid will be calculated from the titration curve obtained by plotting the pH of the solution versus

Content Theory of Motivation Maslow’s Hierarchy of Needs Maslow believed that the importance of human needs depended on what they already had. He believed that the hierarchy started with physiological needs and once those needs were fulfilled‚ then safety needs and security would be sought. Once the person felt safe and secure they would then be motivated by the need to have love and friendship. When those social needs were achieved the person would then look to fulfil their esteem needs

1.0 Introduction: 1.1 Main Issues: After analysing and collecting all the information we could find from our resources‚ we have come agreed to choose Kickapoo (M) Sdn. Bhd. as our researching market. The research question that we have come to investigate is why kids and especially teenagers‚ who were into Kickapoo before‚ do not buy the drink anymore. We choose this market because the generation Y are not loyal about their brands especially when it comes to drinks since there are so many other

Standardize a sodium hydroxide solution by using potassium hydrogen phthalate (KHP) III. When given whether the acid is monoprotic‚ diprotic‚ or triprotic ‚ determine the molar mass of the unknown organic acid. IV. Calculate the Molarity of the Soft drink.

This is also done by the way each scene is composed and designed. In A Clockwork Orange‚ all these concepts help the viewers interpret whether we are who we are because we had no choice‚ or because we were free to make our own decisions. One of the first thing one sees is the way the camera angles to try and involve the audience in

Trimyrisitin to Sodium Myristate to Myrisitic Acid Mandy Boyle Chem 213‚ Section 002 Due Date: December 3‚ 2009 I. Introduction People encounter esters everyday in both natural and synthesized forms. Esters are present in a variety of common compounds‚ from fragrances to animal fat (McMurry‚ 2008). Although these esters can undergo many different important reactions‚ this lab is particularly interested in the hydrolysis of esters into carboxylic acids and alcohols. Companies such as Dove‚ Palmolive
