Wildlife Refuge there is an estimated 10.4 billion barrels on the North Slope (One state ’s free lunch: 28-32). The North Slope covers 89‚000 square miles (Experts say Alaska Oil Drilling Hurts Wildlife: 43). The North Slope extends from the top of the Brooks Range to the Artic coast (Experts say Alaska Oil Drilling Hurts Wildlife: 43).

RECRYSTALLIZATION AND MELTING POINT DETERMINATION OF BENZOIC ACID ANSWERS TO QUESTIONS 1. How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? Fluted filter paper is effective in preventing crystal formation in the filter paper. It is also often used in filtering hot saturated solution used during crystallization. One major advantage of a fluted filter is that it increases

CHEMISTRY EXPERIMENT-1 DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY: Density is a physical

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

reaction is not used to titrate the CaCO3 because it is very slow when the reaction is close to the endpoint. Instead adding an excess of acid to dissolve all of the CaCO3 and then titrating the remaining H3O+ with NaOH solution can achieve the determination of the amount of acid‚ which has not reacted with the calcium carbonate. There are differences between amount of the acid (HCl) added and the amount left over after the reaction is equal to the amount used by the CaCO3. The reaction used to determine
