    Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly.    Q.2. Write the balanced

    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

    AIR-STANDARD ANALYSIS: INTERNAL COMBUSTION ENGINES Air-standard analysis treats the fluid flow through the entire engine as air and approxi¬mates air as an ideal gas. In a real engine inlet flow may be all air‚ or it may be mixed‚ up with 7% fuel‚ either gaseous or as liquid droplets‚ or both. In air-standard analysis‚ even if all fluid in an engine cycle were air‚ some error would be introduced by assuming it to be an ideal gas with constant specific heats. At the low pressures of inlet and
