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

analyze the financial condition of a company‚ we rely on Financial Statements. Financial ratios‚ derived from Financial Statements‚ make this analysis possible. These ratios also come in handy when you need to compare different companies. Let’s first understand what these ratios mean. Then‚ we will look at the different categories they fall into and study the key ratios within each category. What are Financial Ratios? They are expressions that give us the relationship between different components of

The Golden Ratio By : Kaavya.K In mathematics and the arts‚ two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. The golden ratio is an irrational mathematical constant‚ approximately 1.6180339887. Other names frequently used for the golden ratio are the golden section and golden mean. Other terms encountered include extreme and mean ratio‚ medial section‚ divine

Stephany Matos Chem Lab: Chemical Equilibrium Lab 52 Synopsis Iron (III) ions react with thiocyanate ions (SCN-) to form iron (III) thiocyanate‚ FeSCN2+. It is represented in the equation below: Fe3+ (aq) + SCN- (aq) FeSCN2+ (aq) Therefor the equilibrium constant for this reaction is: KC = [FeSCN2+]/([Fe3+]•[SCN-] For this experiment we were able to determine the equilibrium constant KC for this reaction. First we prepared five different mixtures with known initial concentrations of

Determining the Density of Plastics 1) Introduction ⦁ a) Purpose: Determine density of different plastics ⦁ b) Hypothesis: If density is related to the ratio of mass to volume‚ then density can be calculated by using the formula D=M/V. i. c) Background: Density is the physical property that can be used to help identify substances. D=M/V. mass= found using a balanc and labeled in grams and volume=graduated cylinder or taking ( lxwxh ) measured in mL or cm3 2) Materials ⦁ a) List -graduated

Determining Product Cost Managerial accountants must decide what types of managerial accounting information to provide to managers‚ how to measure such information‚ and when and to whom to communicate the information. For example‚ when making most strategic and operating decisions‚ managers typically rely on managerial accounting information that is prepared in whatever manner the managerial accountant believes provides the best analysis for the decision at hand. However‚ there is one major exception
