In this experiment I will investigate the temperature of 50cm³ of water before and after I have added calcium chloride‚ I will gradually increase the amount of calcium chloride by 1 gram to see if there is a significant change. When Calcium Chloride is mixed with water it performs an exothermic reaction which makes new bonds between the salt (Calcium Chloride) and the water. This will therefore make the solution of the reaction increase in temperature. Exothermic reactions transfer energy

potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying more kinetic energy the chance

APPLICATION:FAA / CALPHOS / CALCIUM Apply using 2 tbsp / 1 liters of water. Apply directly to thesoil or to the ground‚ not to the leaves. Keep concoction from direct sunlight. Store in dry coolplace. Cover and keep in a cool place or shadedarea. Drain to extract liquid after 10 to 15days. Transfer liquid into a clean plasticbottles Wait till tiny bubbles disappearbefore sealing the cover before storing.Always leave about ¾ of bottle empty soIMO can breath.

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show

1. Explain the terms area of convergence and area of origin and explain what each term reveals to an investigator. The area of convergence of an impact spatter pattern is the area the individual stains emanated from on a two-dimensional plane. The area of origin of a bloodstain pattern in three-dimensional space may represent the position of the victim or suspect when the stain-producing event took place. These areas can determine and reveal to an investigator the direction of force‚ angle of impact

PRODUCT CONSTANT OF CALCIUM HYDROXIDE ABSTRACT This experiment aimed to determine the solubility product constant (Ksp) of Ca(OH)2 as well as to evaluate the effects of common and non-common ions on its solubility. Ca(OH)2 solids were dissolved in eight various media: distilled water‚ 1.0 M KCl‚ 0.5 M KCl‚ 0.1 M KCl‚ 0.05 M KCl‚ 0.005 M KCl‚ 0.001 M KCl‚ and 0.1 M Ca(NO3)2. The concentration of dissociated OH- concentrations was determined by means of titrimetric analysis with 0.1 M HCl. The [OH-] values

Chemistry – Titration experiment I – Standard Solution Prep Preparation of a standard solution of sodium carbonate Anhydrous sodium carbonate is a suitable chemical (primary standard) for the preparation of a standard solution. Standard Solutions are critical in chemistry because you need to have solutions with an EXACT known concentration and volume. Chemicals/Materials: solid sodium carbonate (Na2CO3) distilled water Apparatus: 250cm3 volumetric flask 250cm3 beaker Glass stirring

AXI DDR3 Controller The AXI DDR3 Controller provides access to DDR3 memory. It accepts the Read / Write commands from AXI and converts it into DDR3 access. While doing this it combines AXI burst transactions into single DDR access where ever possible to achieve the best possible performance from DDR3 memory subsystem. DESCRIPTION KEY FEATURES o High memory throughput achieved via Parallel operation of all the banks and reordering of commands in the controller to ensure the maximum utilization
