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

DNA almost immediately transformed the American Criminal Justice System. Law Enforcement‚ District Attorneys‚ Defense Attorneys‚ Criminal Court and Family Court all work with DNA on a daily basis. DNA that can be utilized in a criminal investigation may be collected from a crime scene in many different forms: skin tissue‚ hair‚ blood‚ semen‚ saliva‚ vaginal fluid‚ anything that may be collected from a human that may contain cells can be utilized and tested for DNA. DNA testing is the most

Replacement Reactions (Data and Calculations) Objective: Classify the chemical reaction through observation‚ which each reagent produce when mixed with another reagent. After careful observation‚ be able to prove each observation using the net ionic equation. Background: First‚ a double-replacement reaction is when two cations in different compound switch anions‚ AX + BZ → BY. If either compounds are insoluble a precipitate occurs‚ and if there is no precipitate formed there is no reaction. Also‚

Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. Introduction In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with hydrochloric acid‚ because it is higher in the reactivity series than hydrogen
