Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

------------------------------------------------- ABSTRACT ------------------------------------------------- The copper reaction experiment was demonstrated by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagents were being added. It was also demonstrated to practice the common laboratory techniques such as methods

Week 10: Oxidation and Reduction Reactions: The Reactions of Copper Data: Part I: Preparing a solution of copper (II) nitrate Initial mass of copper wire: .520g Mass of copper wire after vigorously scouring: .518g Observations of Copper (II) ribbon mixed with HNO3: Solution turned green. Thick brown gas formed. Copper (II) bubbled vigorously. Cu (II) dissolved‚ solution appeared green/blue. After the addition of H2O a blue crusty precipitate formed. Part II: Synthesis of solid copper

You are repeating ’’leader" so often that your essay don’t sound good. Just read it aloud and you’ll understand what I mean. A positive attitude is another essential quality a leader must have in order to do well in office. A leader must see things in a positive light or else everything will not go as planned. For example‚ if a huge crisis was going on and a leader had a mind of a pessimist‚ he would scare "his people" into thinking the situation is way worse than what it really is. On the other

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

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

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
