to the bubbles which rise to form froth on the surface while hydrophilic particles will sink. The froth layer that forms on the surface will then be heavily loaded with the hydrophobic mineral and can be removed as a separated product. A particle and a bubble should have in contact in order for flotation to occur wherein the bubble must be large enough for its buoyancy to lift the particle and stay on the surface. The hydrophilic particles will have much less tendency to attach to air bubbles and so

3.1 What are the technical descriptions of the products or services? The proposed product is called “Micro Bignay Wine”. The product is a fruit wine made out of bignay fruit‚ yeast and sugar. Through the fermentation yeast serves as the catalyst that changes the sugar into alcohol. Bignay has its health benefits. It is rich in anti – oxidants and anti – carcinogenic properties. It is highly nutritious and has a number of medicinal properties. Wine is also a part of relaxation and enjoyment with

Name: Name of lab partner: Date: Title: Determination of the valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction

acid in one and did not add small portions of it as time passed. This zinc-sulfuric acid system was connected to the methyl oleate flask which also contained the Pd/C catalyst. The methyl oleate had an initial mass of 2.352g. As time passed‚ the bubbles produced in the mineral oil system were too few per second. As a result‚ I added an additional mass of 1.2457g of zinc to the hydrogen generator. Throughout the reaction process‚ the round bottom flask containing the methyl oleate and the catalyst

“Water Quality and Contamination” Shirley Tinsley SCI207: Dependence of Man on the Environment Instructor: Oleg Maksimov July 07‚ 2014 ABSTRACT: Experiments were done on the water quality and the contamination of groundwater. First‚ I observed the effects that different pollutants had on groundwater. I predicted that the experiments with the oil and vinegar would create the most contaminations to the water. When the laundry detergent were mixed with the groundwater

Introduction: Calcium hydroxide is a soft white caustic powder used in making mortar‚ cements‚ calcium salts‚ paints‚ and petrochemicals. It is also used in saltwater aquaria to make up kalkwasser/limewater solutions for reef tanks‚ and is used as a pH regulating agent. Notice that calcium hydroxide is divalent and thus has twice the neutralizing power as molecules like NaOH that are monovalent. A Calcium Hydroxide Molecule: Calcium hydroxide is manufactured industrially by adding

Chapter 1 COMPANY DESCRIPTION History of Laundry During the Roman Times‚ laundry was not done at home. It was done at the public “fulleries” by workers called “fullones”. The “fulleries” consist of a big hall with very large basins in the floor. In these basins‚ clothes were soaked and cleaned. Materials were further cleaned by workers who “jumped” or “danced” on clothes while they lean on small walls on either side. On the other hand‚ Ancient Greeks used only water without soap to laundry. As the
