Importance of Calcium Ions Alyssa Foels 12 February 2015 Kilfe Calcium is a cation‚ a positively charged atom‚ and it is essential to all living things. It was first discovered in 1808 by Humphrey Davy. When forming an ionic bond with other elements‚ calcium loses electrons to make its valence shell stable. This means that it has more protons than electrons‚ making it have a slight positive charge (Calcium). Calcium has many roles and functions in the human body. Calcium ions are the most abundant

Ion Exchange Chromatography Discussion: The first exercise preformed in this lab was ion exchange chromatography. The purpose of this experiment is to separate molecules based on their differences in charge. Since it is based on charge the amino acids in the cation exchange column‚ if negatively charged‚ flow through the column first because they don’t want to bind to the sodium ions. The positively charged ions will elute last at the highest ph because they bind to the negatively charged beads

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). The term “dragon fruit” is used in English

Introduction: Fruit of the Spirit Turn in your Bible to Galatians 5:22. This is a relatively familiar verse. Ask any child fresh out of a bible-learning program—Bible School‚ years of Sunday School and Awana‚ whatever—to name the fruit of the Spirit‚ and they can probably tell you. “The fruits of the Spirit are love‚ joy‚ peace‚ patience‚ kindness‚ goodness‚ faithfulness‚ gentleness‚ and self-control.” They can recite those words with huge smiles on their faces‚ ticking them off on their

Dragon fruit in Vietnam has three main varieties: red-skinned fruit with white flesh‚ red-skinned fruit with red flesh and yellow-skinned fruit with white flesh. Since the white-fleshed dragon fruit (or Pitaya) can grow stronger‚ larger and produce sweeter fruit than other varieties‚ they are much more planted in the Vietnam. Dragon fruit with red and yellow flesh are also popular‚ but the area for red-fleshed dragon fruit in the rural areas in Vietnam is trivial and its productivity equals only
