an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it is not expensive and can easily be removed for the reaction. The acetic acid and isopentyl alcohol are removed by extraction with sodium bicarbonate and water. The limiting reagent is isopentyl alcohol. A limiting reagent is completely consumed when

In this case study‚ Patina is the seller and Luca is the buyer under an FOB (Free on Board) agreement. General picture of a FOB contract can be congregated from the case of Wimble & Sons v Rosenberg & Sons which describes it as a contract for the sale of goods where the seller which in this case is Patina who agrees to deliver the goods over the ship’s rail and the buyer or Luca in this stance agrees to convey it overseas. According to English law‚ the case of Pyrene v Scindia defines a classic FOB

carbohydrates and proteins‚ as well as the action of an enzyme on specific molecules. Introduction Unknown biological molecules can be correctly identified using various tests‚ including colorimetric chemical tests. Colorimetric tests are when a chemical reagent‚ such as Benedict’s‚ is used on a substance or solution and a certain color change occurs as a response. Carbohydrates and proteins‚ two of the larger types of biological molecules‚ also called macromolecules‚ are actually chains of molecules called

If you’re looking for a way to kill the basketball league‚ you should call a man named Perry Johnson of Chicago‚ Illinois. I think he’s found it. Around 3 years ago‚ Perry’s 16 year old son‚ Lucas‚ got a steal and he started running up the court. The problem was‚ Lucas normally did not get that much playing time and did not know how to play basketball. In fact he had never stolen the ball before. So‚ when he went up for a layup he completely missed the hoop and fell on his head and got a concussion

EXPERIMENT NO. 12 DIGESTION IN THE STOMACH ABSTRACT____________________________________________________________________________ Digestion refers to the mechanical and chemical breakdown of food into smaller components that can undergo absorption. The objective of this experiment is to investigate mainly the process of digestion in the stomach. The conditions at which the enzymes responsible for the digestion process were determined. Also‚ the total and free acidity of gastric juice of the sample

Biruiet Test: Procedure Instead of the Biuret Reagent‚ the following may be used: * Fehling’s Solutions A and B * Sodium hydroxide and copper (II) sulphate solutions 1. Add 2 cm3 of the liquid food sample* to a clean‚ dry test tube 2. Add 2 cm3 of Biuret Reagent. Alternatively: * Use sodium hydroxide solution and copper sulphate solution instead. Add 1 cm3 of sodium hydroxide solution (40% or bench solution) and 1% copper (II) sulphate solution dropwise – drop by drop - to

This change occurred because the concentration of the acid and base increased. The observed temperature change in experiment 4 was 3.30 °C‚ which was half of the one that was given to the team. This change occurred because the amount of the limiting reagent in this experiment is half of the one that was given to the team. The observed change in experiment 5 was 7.05 °C‚ which was slightly higher than the one that was given to the team because a different acid was used with different

Nuclear Power After Fukushima” by Lucas W. Davis in 2011‚ attempts to break down the question and provide detailed analysis on this issue with collected data and professional knowledge. In particular‚ Davis’s research focuses on the costs during nuclear power generation and its competitive advantages in long run. On a broader spectrum‚ the writer considers both benefits and risks nuclear power brings to human life‚ and finally comes to a conclusion. As Lucas W. Davis suggests‚ the continuously
