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

Zenith TurbosPort models‚ were sometimes described as "laptops"‚ their size and weight were too great for this category. The first commercially available portable computer was the Osborne 1 in 1981‚ which used the CP/M operating system. Although it was large and heavy compared to today’s laptops‚ with a tiny CRT monitor‚ it had a near-revolutionary impact on business‚ as professionals were able to take their computer and data with them for the first time. This and other "luggable"

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

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

A pressure group is an association that may be formal or informal‚ whose purpose it is to further the interests of a specific section of society or to promote a particular cause. Pressure groups normally fall under 3 classifications‚ sectional which represent a specific section of the public‚ e.g. Age UK‚ promotion which promotes a particular cause‚ e.g. Greenpeace and finally dual-function who are a combination of both sectional and promotional‚ e.g. Countryside Alliance. Pressure groups can also
