The objective of this experiment is to demonstrate and explore how chemical reactivity is affected by variations in these properties. ~Atomic radius‚ ionization energy‚ electron affinity‚ effective nuclear charge and electronegativity are a just a few such parameters. Part A of this lab deals with the solubility of dissolved ions. The two primary factors involved when an ionic solid is dissolved (dissolution) in water are dissociation and solvation. --Dissociation‚ the separation of the

EXPERIMENT 4B: THE MENDELEEV LAB OF 1869 Materials: 30 element cards‚ periodic table Aim: How can we identify elements based on their propeties? Background: Russian chemist Dmitri Mendeleev is generally credited as being the first chemist to observe patterns emerge when the elements are arranged according to their properties. Mendeleev’s arrangement of the elements was unique because he left blank spaces for elements that he claimed were undiscovered as of 1869. Mendeleev was so confident

CHAPTER I INTRODUCTION BACKGROUND OF THE STUDY An easy and practical way to make your shoes shinier with the use of alternative plant. A shoe polisher can be a wax or a cream that can be applied directly to shoes. Applying shoe polish will not only just make your shoes shine but it also protects your shoes from any liquid substance especially during rainy days. Shoe polish is usually flammable‚ can be toxic‚ and‚ if misused‚ can stain skin. It should be used in a well-ventilated area with care

Semiconductors: Band Gap of Germanium and the Hall Effect Friday‚ Section 006 TA: Yilikal Ayino John Greavu with Daniel Erickson & Kevin Haar February 14‚ 2014 PreLab With the new understanding of quantum mechanics and solid-state physics in the 1930’s came the development of semiconductors. Semiconductors are materials such as silicon and germanium in which the current density is non-zero‚ unlike an insulator‚ yet still several magnitudes smaller than that of a conductor. There exists a significant

Water Crisis in Afghanistan It makes up approximately 70 percent of the Earth that we inhabit. You may find yourself “up to the neck in it” at any given point‚ seeing as humans can be composed almost entirely of it. Water is all around us‚ and is essential to the ongoing cycle of life. Although water may seem abundant throughout the Earth and atmosphere; the amount of clean‚ useable water is an everyday crisis for some of the drought stricken‚ less fortunate countries. While the Oceans hold roughly

Economy overview: Turkey’s dynamic economy is a complex mix of modern industry and commerce along with a traditional agriculture sector that still accounts for about 30% of employment. It has a strong and rapidly growing private sector‚ and while the state remains a major participant in basic industry‚ banking‚ transport‚ and communication‚ this role has been diminishing as Turkey’s privatization program continues. The largest industrial sector is textiles and clothing‚ which accounts for

as a result of synthetic nitrogen fertilizer use.[4] Fertilizers typically provide‚ in varying proportions: six macronutrients: nitrogen (N)‚ phosphorus (P)‚ potassium (K)‚ calcium (Ca)‚ magnesium (Mg)‚ and sulfur (S); eight micronutrients: boron (B)‚ chlorine (Cl)‚ copper (Cu)‚ iron (Fe)‚ manganese (Mn)‚ molybdenum (Mo)‚ zinc (Zn) and nickel (Ni) (1987). The macronutrients are consumed in larger quantities and are present in plant tissue in quantities from 0.15% to 6.0% on a dry matter (DM)
