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

about thirty thousand Persian boys to “speak the Greek language and to use Macedonian weapon” [Plutarch]‚ the very same boys who would eventually be known as his ‘Successors’. Through these incidents‚ we can see that Alexander showed a strong determination to instill his ‘Policy of Fusion’ by going as far as to alter his lifestyle and his army. Many Macedonians were unhappy with his kind attitude towards the Persians though many had kept the resentment in the silence of their

8. a) The melting of the ice sheet in greenland may bring opportunities for people and communities rather than a negative threat. One advantage of of the melting ice sheet may be that it brings in a better income for people. Melting ice sheets means that more land is being uncovered exposing expensive rocks and riches such as zinc and lead. The reveal of land and rock means that people and communities are able to mine this will give people a better income and lifestyle. Mining can be done in all
