Brittany Roberts AP bio WATER ESSAY The first thing water reminds us of is the clear liquid in our water bottles. However‚ water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties‚ water was able to start life on our planet. Water covers about 3/4 of the earth. In nature‚ water naturally exists in all three physical states of matter—solid‚ liquid and gas. Water’s extraordinary properties are emergent properties resulting

Static Electricity Everything is made up of tiny particles called atoms. The atoms are made up of even smaller parts called protons‚ electrons and neutrons. Protons have a positive charge (+)‚ electrons have a negative charge (-) and neutrons have no charge at all‚ they are neutral. Atoms normally have the same amount of electrons and protons‚ making them neutral and having no charge. When rubbing things together‚ electrons can move from one atom to another‚ resulting in some atoms having extra

High Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography

Preparing to Conduct Business Research: Part 3 RES/351 May 20‚ 2013 Kim Gravelle‚ PhD Preparing to Conduct Research: Part 3 Team F’s Pet Palace wants to set itself apart from the competition. During the planning process‚ Pet Palace’s managers have come across a dilemma: pet supply sales are down because of competition from the online marketplace. This proposal will show that a small-scale‚ exploratory study is appropriate and necessary to make the steps required to correct this dilemma.

Lab report: Viscosity of Liquids Introduction This experiment focuses on measurements of different trials of various concentrations. The collected data is used to compare and contrast to the ideal binary solutions and their components. The Ostwald viscometer is a useful laboratory equipment to measure the viscosities of many binary solutions. Background Molecules have the ability to slide around each other‚ result in a flow. Such a flow has a resistance called viscosity. Microscopically

DETERMINATION OF THE WATER OF CRYSTALLISATION April 4‚ 2012 OBJECTIVE: Chemical compounds that contain discrete water molecules as part of their crystalline structure are called hydrates. Hydrates occur quite commonly among chemical substances‚ especially among ionic substances. More often than not‚ such compounds are either prepared in‚ or are recrystallized from‚ aqueous solutions. Hydrates exist for ionic compounds most commonly‚ but hydrates of polar and non polar covalent molecules are also known
