Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

is based on (a) simple‚ rapid and complete extraction of acids from an oil test portion into reagent (0.05 mol dm–3 triethanolamine (B) in the mixture of 50 % H2O + 50 % 2-PrOH) and (b) indirect titration of acids in BH+ form against aqueous alkali in the presence of a phenolphthalein indicator. Suitable metrological parameters of acid value determination have been obtained. The advantages of the method are (i) absence of a toxic solvent‚ (ii) extraction and titration of acids at room temperature

body cells. Meiosis results in the formation of either gametes in animals or spores in plants. The cells formed have half the chromosome number of the parent cell. Mitosis is best observed in cells that are growing at a rapid pace‚ such as in the onion root cell tips or at Drosophila giant chromosome. The root tips contain a special growth region called the apical meristem where the

The poem‚ “Monologue for an Onion” written by Sue Kim‚ the onion is a metaphor and is the whole poem is written about it and based off of it. The basic main viewpoint of the poem is about the feelings and thoughts that onion experiences when being handle by the person or more specifically when it is being cut. The poem revolves around the whole idea of how the onion feels and thinks as the person cuts away at it and how it reflects on the actions of the person and the person themselves. Sue Kim’s

MONOLOGUE FOR AN ONION: AN ANALYSIS Cutting an onion breaks cells in its skin causing a reaction that results to the formation of volatile sulfur compound which‚ when mixed with tears coating our eyes‚ becomes sulfuric acid. This triggers the tear ducts to produce more tears to alleviate the imbalance in acidity the irritant has caused; the longer the eyes are exposed to the acid the greater the quantity of tears produced. Sue Kwock Kim uses this certain property of an onion to tackle a specific

Crystallization: Lab Report Theory/Introduction The purpose of this lab is to understand the concept of purification through crystallization. Crystallization is the process of purifying a substance‚ with the most adequate solvent. The process of crystallization came to be based on the principle of solubility. First‚ we must choose a solvent. The solvent is crucial to crystallization because it’s what will allow impurities to dissolve. Therefore‚ when selecting a solvent it is important that it

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

Formal Lab Report #1 I. Basics Title of the Experiment: The Empirical Formula of an Oxide Authors: Section Number: Chemistry Location and Date II. Abstract The aim in this lab was to determine the empirical formula of an oxide of magnesium through combustion in air. This was achieved by heating an established mass of magnesium in air inside of a crucible‚ ultimately attaining a compound that contained Mg and O. The major result of the experiment was the empirical formula of the oxide of magnesium
