However‚ Dade is attacked by the hacker (Acid Burn) on the same network‚ and is eventually kicked off. During the conversation‚ Dade identifies himself by the new alias‚ Crash Override. Dade enrolls at Stanton High School‚ where he meets the beautiful Kate Libby (Angelina Jolie)‚ who is responsible for taking him on a tour of the school. Dade is being told about the pool on the roof that results of being locked on the roof with the other several students during rainstorm. He learns that Kate is

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

Lab #4: Aqueous Reactions Introduction: In this experiment we studied the two different types of aqueous chemical reactions‚ double replacement and single replacement. In a double replacement reaction one or both of the products is an insoluble ionic compound or otherwise known as a precipitate; or a non-electrolyte; or a gas. In a single replacement reaction there is typically a metal and an ionic compound consisting of a metal cation and a non-meatl anion. Singel replacement ractions occur when

High School Students’ Conceptions about Energy in Chemical Reactions (focusing only in exothermic and endothermic reactions). Aim The aim of this study is to investigate students’ understanding of the energy concept in chemical reactions particularly in endothermic-exothermic reactions. Both qualitative and quantitative methodology was used for this investigation. A twenty-item multiple choice test was developed about the topic to measure the students’ understandings. This concept test was

REACTION PAPER ON THREATS TO NATIONAL SECURITY With the events between the United States of America and Syria leading towards a possible world war‚ never has national security become so vital. There are various factors that pose threats to the sovereignty of our country. Peace talks between President Benigno Aquino III’s administration and the Moro Islamic Liberation Front are once again at a standstill‚ with the MILF having doubts on forging a wealth-sharing deal with the government.

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

metals arranged in order of their reactivity based on displacement reactions‚ reduction of their oxides by hydrogen or carbon‚ the relative ease of decomposition of their compounds and reactions with oxygen‚ dilute acids and water. The higher up a metal is in the reactivity series‚ the more reactive it is. In the experiment conducted‚ the three metals‚ magnesium‚ zinc and copper each had to undergo displacement reactions and reactions with water‚ oxygen and dilute acids‚ to arrange them in the order
