Since I was young‚ I have striven to achieve my goals; I call it a "determination to succeed." Without a "determination to succeed‚" giving up in life‚ when a situation seems impossible to overcome‚ becomes second nature. The methods one uses to overcome the challenges faced in life affects how one acquires success. For example‚ my ancestors did not overcome their struggle for equality without self-determination to better their lives. Thus‚ their lives have been an inspiration for me. The motivation

Determination of the Waters of Crystallisation/ Water of Hydration‚ In Hydrated copper (II) Sulphate Introduction In nature there are some salts that will have water in their crystalline structure. These salts are commonly known as hydrated salts. Hydrated Copper (II) sulphate is one of these‚ as suggested by the use of the word hydrated in its name. Its molecular structure is shown below. The water that is chemically combined into their structure is called the water of crystallisation.

Diffusion Lab Research Question: How does the amount of water in a beaker affect the rate at which food coloring diffuses to the bottom of the beaker? Independent Variable: Height of water in beaker (Inches) Dependent Variable: Rate of diffusion (seconds) Controlled Variables: * Size of beaker * Temperature of water (23°C) * Type/color of food coloring * Person Timing * Environmental conditions Materials: * Beaker(well over 4 in tall) * Food coloring * Tap water(23°C)

SHC of water • To see how accurately I can measure a known quantity Research Question • Will the experiment carried out give us a good approximation of the SHC of water? Hypothesis • The result we will get as the SHC of water will not be exactly the same as the literature value‚ but will be a very close figure to the literature value of the SHC of water as there will be some limitations to our experiment. Variables Independent: temperature of water Dependent: SHC of water Controlled:

9/15/11 AP Chemistry Dr. Isotone Lab 1: Determination of the Empirical Formula of Silver Oxide Lab Objective: In this experiment‚ the percent composition and empirical formula of silver oxide will be determined. Silver oxide will be heated until it decomposes to silver metal and oxygen‚ and the percent calculation and empirical formula can be calculated based on combining the ratios of silver and oxygen in the reaction. Summary of Lab Procedure: 1. Set up Bunsen burner on

Determination of pKa James McDuffie ABSTRACT: In this lab‚ the pKa of unknown solution #4 was measured Introduction: This lab focused on the equilibrium constant‚ Ka. Ka is associated with chemical properties of acids. The equivalence point will be reached once the moles of OH- equal the moles of HA and once this point is reached‚ the PH changes very quickly. With the results‚ a titration curve should be produced. Experimental Section Materials and Methods: A buret with NaOH solution

and bilirubin is formed by the reduction of biliverdin. In contrast to iron and globin‚ which can be metabolically reused‚ bilirubin is an end product and toxic product that should be efficiently eliminated from the body. As the bilirubin formed is water insoluble‚ it binds to albumin upon entering the blood as unconjugated or free bilirubin. Upon the bilirubin binding to albumins‚ it is transported to the liver‚ where it undergoes conjugation and excretion. Upon its separation from albumin on hepatocyte
