In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006).

First‚ the buffer was prepared by using the formula as follows: Figure 1: Calculation for prepare 0.1 M potassium phosphate buffer at pH 6 3.4007g of potassium phosphate was weighed and placed in 300 mL beaker. Then‚ 125 mL of water was added into the beaker that contained potassium phosphate. The mixture was dissolved using the stirring rod‚ and then the magnetic stirring bar was placed in the beaker for further dissolve when measuring the pH. The pH meter was used to measure the solution

The first one is to strengthen the knowledge on the dynamics of a supply chain via a deep review of the Bullwhip Effect. The second one is to build a new framework abled to classify the causes of the Bullwhip effect. Furthermore‚ this framework can distinguish layers and mechanisms that lead to Bullwhip Effect and so help managers to better understand
