    Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction

    The goal for this experiment is to determine which out of the four balanced chemical equations best represent the thermal decomposition of sodium bicarbonate. The guiding question will be answered with the outcome of the sodium bicarbonates thermal decomposition and it being plugged in into the four balanced chemical equations. John Dalton atomic theory explains two fundamental laws of chemistry which are the law of conservation of mass and the law of definite proportions. The atomic theory states

    Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

    The aim of the experiment was to examine the effects of consuming lactate before and during a prolonged exercise. The data shows that the consumption of the lactate actually did work and the performance of the subject was better than the previous three experiments of dieting. This was due to the lactate that was consumed in the CytoMax. Azevedo‚ Tietz‚ Two-Feathers‚ Paull‚ and Chapman (2007) state that CytoMax contains polylactate which speeds up the delivery of substrates and is thought to help

    the food coloring on top of the vegetable oil. Then we put the Alka-Seltzer in it. When it went in there it pushed the food coloring up into the vegetable witch made it go slow so it made bulbs of food coloring so it looked like a lava lamp. Why did this happen because‚ well the Alka-Seltzer reacted with the water naturally so the fizz pushed the food coloring up. So when it went up it ran into the vegetable oil witch is thick so it made it go into bubbles and if you have ever watched a lava lamp the
