Experiments 4A-C: Synthesis and Component Analysis of an Iron (III) Oxalate Complex My Name TA‚ Section B## Work Performed on 10/23‚ 10/30‚ & 11/4‚ 200# Report due Tuesday‚ November ##‚ 200# 1. Abstract This experiment initially involved the synthesis of an iron (III) oxalate complex with the general formula Kw[Fex(C2O4)y]·zH2O. The variables x‚ y‚ and z were determined through the duration of the entire experiment. From 1.2000g of Fe(NH4)2(SO4)2 were synthesized 1.1###g of K3[FeIII(C2O4)3]·3H2O

Dragon fruit‚ also known as pitaya or pitahaya‚ belongs to the Hylocereus genus of the Cactaceae family. It is recognized as leathery‚ slightly leafy – skinned sweet fruit of many cactus species rooted from Mexico‚ which was believed to be then brought to Central America by the European. Nowadays‚ dragon fruits are widely cultivated in the United States‚ the South East Asia region‚ Israel‚ Australia‚ Cyprus‚ as well as the Canary Islands (Morton‚ 1987).

Important Ions in the Body and the Roles They Play Everyday Functions of the Human Body The human body uses many forms of energy to conduct daily activities. These activities can be ones that we are doing physically or they can be as basic as the breakdown of enzymes within our body or the digestion of food. Chemical energy‚ electrical energy‚ mechanical energy‚ and electromagnetic energy are a few but important forms of the type of energy utilized by the human body. Ions play an important

A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can

Aims The aims of this investigation are: 1. To find the rate equation of the reaction of hydrogen peroxide and iodide ions. This will be achieved by using an iodine clock method and colorimetric analysis. 2. Draw a graph of rate against concentration for each reactant (Hydrogen peroxide‚ potassium iodide and H+ ions). 3. Finding the order for each reactant 4. Finding the rate-determining step. 5. Proposing a mechanism for the reaction. 6. Using Arrhenius’ equation to find the activation
