Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

processing unit (CPU) on a single integrated circuit (IC)‚ or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system. The advent of low-cost computers on integrated circuits has transformed modern

Aim: The aim of this experiment is to convert copper metal through a series of intermediate copper compounds back into copper metal. By weighing the copper at the beginning and at the end of the experiment the percentage yield can be determined. Method: The experiment was carried out as outlined in the practical manual. Results: Table: showing masses: Mass copper wire 0.2510 Mass crucible 28.9257 Mass watch glass 19.6213 Mass watch glass + copper 19.7890 Mass copper

(Matsumoto‚ 2006). However‚ emotional expressions can be controlled in order to mask what individuals truly feel and this is known as “Display Rule” (Gnepp and Hess‚ 1986). The understanding of display rules and emotional expression is of paramount importance as it affects human interaction and the relationship between self and other. Display rules refer to a set of social norms prescribing the appropriateness of expressing an emotion in particular situations (Saarni‚ 1999). This means that

In conclusion I found out that the ions present in my sample where sodium‚ sulphate and bromine. The Cation was sodium and the Anions where sulphur and bromine this means that my sample was sodium sulphate or sodium bromide. Evaluation My experiment went very well but if I could redo this I would make some changes. The Mummion that I had filtered was not completely clear‚ so I would filter this couple of times before putting it into an evaporating basin. There may have been some measuring
