Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average

equation is an important second-order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves‚ light waves and water waves. It arises in fields like acoustics‚ electromagnetic‚ and fluid dynamics. Historically‚ the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d’Alembert‚ Leonhard Euler‚ Daniel Bernoulli‚ and Joseph-Louis Lagrange. Figure 1-Wave Diffusion Wave equation has many applications

What formal features of Romeo and Juliet might lead critics to categorise it as a tragedy? To analyse the formal tragic features of Romeo and Juliet which could lead to its critical classification as a tragedy first and foremost is the understanding of the formal definition of tragedy as given by Aristotle and the understanding of it with regards to Senecan tragedy which provided the model for Elizabethan tragedy‚ and the contemporary view of tragedy. Aristotle’s formal elements of tragedy

water‚ soil‚ temperature and light intensity. Biotic factors are the living components in the ecosystem such as animals and plants. In an ecosystem‚ the living organisms live together in their non-living environment and function as a unit. This dynamic system starts with species‚ populations‚ ecosystems‚ communities and biosphere. A species is a group of organisms that look alike and have similar characteristics‚ share the same roles in an ecosystem and are capable of interbreeding to produce

Input control There are different actions needed before the execution of the marketing plan. Financially‚ more funds are needed for advertising MIXY to increase awareness‚ new product development‚ and better colors for the packaging. MIXY is not advertised and it needs to be in a larger product line to compete better. Also‚ as the packaging is made by the same supplier as CL‚ it should differ to be easily recognized. More expenditure is also needed for the R&D as the company is strong in

Angela Campoli ENG 4U1 Ms. Simon Father Leo J. Austin CSS Nov. 19‚ 2014 The Loss of Humanity in 1984 Every human being holds an intrinsic set of natural behaviours which ultimately affect how they perceive their surroundings. For the majority‚ these behaviours come naturally so they have no control over them‚ unless they are negatively influenced to do otherwise. In George Orwell’s dystopic novel 1984‚ the citizens of Oceania are unfortunately controlled by the Party in every way possible. The

These differences are perhaps most highlighted in the medical field where stereochemistry of a molecule can be the difference between having a medically active‚ effective drug and a toxic‚ potentially

Introduction: The purpose of the first experiment was to practice obtaining accurate and precise results by doing combustion analysis to find the amount of carbon dioxide and water released and the amount of fuel consumed. To identify the amount of carbon dioxide‚ water and burner consumed there were three equations used to find it. Equation 1 shows how much carbon dioxide was released. Mass of carbon dioxide = m2 - m1 Equation 1 was used as an experimental procedure created to help find out
