Lab Report Background Information: Magnesium is an alkaline earth metal that has the symbol Mg. Magnesium is a fairly strong‚ silvery-white‚ light-weight metal (one third lighter than aluminum). In a powder‚ it heats and ignites when exposed to moisture and burns with a white flame that is harmful to the eyes. It is difficult to ignite in bulk‚ but once ignited‚ it is difficult to extinguish. Magnesium Ribbon is a long strip of magnesium metal about 3 millimeters wide and 10 meters long with

esterification reaction that was carried out in this lab is shown in figure 1. It worth mentioning that the by-product of such reaction is water. In organic chemistry‚ the reaction in which water molecule is released is known as condensation reaction (Hornback‚ 2006). Figure1 is drawn using Chem Sketch software. a) b) Figure 1: Typical Fischer esterification reaction (a) in comparison to the specific esterification reaction used in this lab (b) The reaction can also be categorized in terms of

controls used in this lab were heat‚ wind and light (sun). 3. What environmental factors that you tested increased the rate of transpiration? Was the rate of transpiration increased for all plants tested? -Wind and heat were the factors that consistently increased the rate of transpiration. This was shown to happen in all of the plants. 4. Did any of the environmental factors (heat‚ light‚ or wind) increase the transpiration rate more than the others? Why? -Wind and heat increased the transpiration

of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion is present in the K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O using

Cross-cultural Management 380 Assignment One ; Joe Willis Feeling the Heat of Thailand By Cécile Branco-cote Due on October 7 1- Reading the case study‚ there is two challenges that stakeholders have identified as a threat to the efficiency of Thailand’s Fasco Motors subsidiary. The first one is the lack of trust between the three new executives and the Thailand’s team members. The second challenge‚ deriving from the first‚ is the lack of affective communication between members. The three
