French and Raven came up with five different bases of power. Coercive‚ legitimate‚ reward‚ referent‚ and expert are the five types of power. Someone can create power through one or more of these bases. There is the possibility that one base power may undermine another. One must learn how to use these powers in a positive way to create a positive relationship. Coercive power gives employers power by having the employees fearful of punishment. Termination‚ demotion‚ or loss of rewards could be

Experiment Separation of Organic Compounds by Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds

The five bases of power are divided into two groups; formal power and personal power‚ and further subdivided into five specific categories under each group. Categories of formal power are coercive power‚ reward power‚ and legitimate power‚ and they come from the authority of one person over another. Categories of personal power are expert power and referent power‚ and they come from one’s characteristics rather than one’s authority. “Coercive power base depends on fear of the negative results from

more alluring than the prospect of conquering a mountain. At 1:15 a.m. I emerged from my tent with my boots laced‚ my ice-axe stowed‚ and my headlamp glowing. I was ready for this mountain‚ rearing to begin the ascent up its face. Before leaving base camp‚ my guide had a few words to share with the team. We gathered around him‚ and he began. “This will not be an easy climb‚” he warned‚ “And not all of you will reach the summit. If you feel disoriented‚ I will send you down. If you are slowing‚

Bases are substances that are in aqueous solution‚ are slippery to the touch‚ taste bitter‚ change the color of indicators Examples turn red litmus paper blue and react with acids to form salts‚ promote certain chemical reactions. General properties of a base are Concentrated or strong bases and are caustic on organic matter and react violently with acidic substances. Also bases can are bitter in taste. And the pH of a basic solution at standard conditions is greater than seven. Strong bases are

ACIDS & BASES Acids/Bases Basics Acids and bases are common solutions that exist everywhere. Almost every liquid that we encounter in our daily lives consists of acidic and basic properties‚ with the exception of water. They have completely different properties and are able to neutralize to form H2O‚ which will be discussed later in a subsection. The table below compares the different properties between them: pH Scale Since acids increase the amount of H+ ions present and bases increase
