STK 1084 Inorganic Chemistry I‚ LU 3 Oxidation – Reduction Reactions‚ Prepared By: Dr. Tay Meng Guan‚ Faculty of Resource Science and Technology‚ Universiti Malaysia Sarawak. LU 3 Oxidation and Reduction Reactions 3.1 Ideas of Oxidation and Reduction Oxidation of an atom can be occurred in the following conditions: 1. Losing an electron from the orbitals. e.g.: A A+ + e- 2. Adding an electronegative element (e.g.: F‚ Cl‚ Br‚ O) to a molecule. e.g.: A + F AF 3. Losing hydrogen

A2 Art Essay: Why was the work of Andy Warhol and Roy Lichtenstein immediately popular in the 1960’s? Roy Lichtenstein rapidly became popular in the 1960’s with his very original pop art pieces which he based many on comic strips‚ advertisements or newspapers. These tended to be the main inspiration for his work; this is because the subjects would tend to be exceedingly emotional and melodramatic. He became an idol to the American culture by adding in comic book characters which were very

OXIDATION AND REDUCTION Oxygen makes up only about 20% of the air‚ yet is the essential component for so many reactions. Without it fuels would not burn‚ iron would not rust and we would be unable to obtain energy from our food molecules through respiration. Indeed animal life on the planet did not evolve until a certain concentration of oxygen had built up in the atmosphere over 600 million years ago. The term oxidation has been in use for a long time to describe these and other reactions where

Oxidation of Cyclohexanol Introduction: The oxidation of cyclohexanol involves using household bleach to oxidize this secondary alcohol and produce a ketone product‚ cyclohexanone. Oxidation-reduction (redox) reactions occur when the oxidation state of atoms change due to a transfer of electrons. Oxidation occurs when electrons are ‘lost’ to the formation of bonds and reduction occurs when electrons are ‘gained’ in the braking of bonds (Levine). Using this reaction and its product‚ a redox experiment

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side

Finally‚ I will conclude with an actual demonstration of screen-printing in the Museum’s basement studio.) In coming weeks‚ you’ll have an opportunity to hear much more about the cultural-historical context for Andy Warhol’s work from two exceptional area scholars‚ beginning next Friday evening with a lecture by my colleague at GV‚ Dr.

Andy Warhol Best-known for his silk-screened photographs of Marilyn Monroe‚ Jacqueline Kennedy‚ Elizabeth Taylor and Elvis Presley‚ Andy Warhol accustomed artists and critics worldwide to use the art of borrowed imagery. Replicating previous artwork from decades before him‚ Andy Warhol became the founding father of appropriation‚ that has now become a symbol of postmodernism‚ and an artistic approach for an era in which concepts of innovation and authorship are thoroughly questioned. This theory

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom
