Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

Are They Normal Fish? In Finding Nemo‚ it is evident there are fish whom have a mental illness. The illnesses in the movie range from OCD to schizophrenia. One can tell if a fish in the movie has a mental illness from the fish’s actions. Marlin‚ Nemo’s father‚ is suffering from depression and PTSD. This can be seen by observing the way Marlin acts towards Nemo going to school. Marlin is very overprotective of Nemo. Along Marlin’s journey to find Nemo‚ Marlin meets another fish named Dory. Dory

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

Chemical Equilibrium: Finding equilibrium constant‚ Kc 1 Abstract Chemical reactions are accompanied with formation of products. A reaction can be reversible or forward according to the rate of formation of product. However‚ they do not reach completion and the mixture remains in equilibrium. This theory help us the study the existence of equilibrium constant‚ Kc. This constant is temperature dependent‚ and it must be calculated at given temperature. This equilibrium constant

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
