Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid Aim. In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by

CONCENTRATION - The Tunnel Vision Of Mind. Concentration is the art of being focused at what one is doing without permitting any form of hindrance. It is an essential skill that every individual develops as he/she grows up. It has to be developed by one’s own effort and cannot be injected into one’s mind. Of course‚ at times‚ people may guide them as to how to gain concentration‚ but the key to having full concentration is in our hands.

AbstractThe rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For

Concentration Camps in Vienna The Auschwitz concentration camp complex was the largest of its kind established by the Nazi regime. It included three main camps‚ all of which deployed incarcerated prisoners at forced labor. One of them also functioned for an extended period as a killing center. The camps were located approximately 37 miles west of Krakow‚ near the prewar German-Polish border in Upper Silesia‚ an area that Nazi Germany annexed in 1939 after invading and conquering Poland. The SS authorities

Conductor Investigation Calvin Chang 8.2 Stage 1: Planning the Experiment Introduction ! By “electric current”‚ I mean by the rate at which electric charges moves through a circuit‚ the electric charges can either be ions or electrons. They are measured in ammeters and the unit that is measured in is ampere which is the number of charges that passes through per second. There are many factors which would affect the electric current‚ like the voltage of the battery‚ the type of wire you are using‚ how long

Have you ever wondered how industries are determined oligopolies or monopolies? In this paper I will discuss how concentration ratios are used to determine total market shares within four specific industries. I will also discuss the levels of competition within those industries and how oligopolies can benefit society. Case‚ Fare‚ and Oster defines concentration ratio as the share of industry output in sales or employment accounted for by the top firms (2009). They are used to measure

The formation of these camps were notorious for being one of the most unnerving events in not only WWII‚ but even world history. What was truly intriguing about concentration camps were the ignorance about it’s existence considering concentration camps alone killed nearly a million of their prisoners. The treatment that citizens like Jews had to experience still
