Crash Course in Density Jonathan Cerreta Chemistry As flight 143‚ a twin engine 767‚ was passing over Red Lake on its was to Edmonton‚ Canada‚ the left front fuel pump warning light went on. There were a few possibilities for this to happen‚ such as the fuel pump failing‚ a fuel line clogging‚ or a empty fuel tank. The former two were easily dealt with‚ since the plane could fly without one fuel pump. However‚ the last possibility was horrifying. After a few minutes‚ the second fuel pump

Report Determining the Density of Various Liquids and Solids The purpose of this experiment is to determine the weight (density) of certain liquids and solids in chemistry. These liquids include; Water‚ Hexane‚ Carbon Tetrachloride‚ and solids include; Copper‚ Zinc‚ Lead and‚ Aluminum. It’s important to know the weight of these products so you can properly conduct experiments and make clear observations. Different techniques will be used to determine these densities and one in particular is

SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

OBJECTIVE To learn the concept of separating organic compounds by utilizing the concept of acid/base chemistry in so that separation can be done. INTRODUCTION Using acid base chemistry in the separation of substances can be a quite useful technique in organic chemistry. A basic extraction can be carried out by applying a hot solvent such as water to a dry substance like coffee. This will allow for the extraction of caffeine and flavor from the coffee beans. Acid base chemistry can be useful in separating

Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte (wekipedia). The first step will be measuring and

the earth’s surface is covered in water‚ leaving only 30% as land; however within this portion exist many physical features that restrict human habitation. Only around 11% of the earth’s surface poses no serious threat to human settlement and 80% of the world’s 6.7 billion people live on 10% of the earth’s surface. The majority of the world’s population reside in the Northern Hemisphere; the sole reason for this being that the majority (63-70%) of the world’s total land mass is situated there

Density Matters: The Effects of Urban Growth Boundaries on Florida Urban Densities Prepared by Submitted to ___ Executive Summary Urban growth boundaries (UGB) are a growth management tool adopted from early English land use traditions to categorize land use. UGB’s are boundaries that clearly delineate the limit of the urban density growth permitted and supported by the issuing municipality. Florida instituted the Growth Management Act in 1985‚ mandating local comprehensive
