The oxidation number of Cr changes during the reaction from ________ to ___________. Because of this change, chromium is reduced / oxidized (circle one). The oxidation number of the alcoholic carbon changes from ________ to ___________. Because of this change, the carbon is reduced / oxidized (circle one).

Homework Answers

Answer #1

the oxidation number of Cr changes during the reaction from +6 to +4 . because of this change, chromium is reduced .

the oxidation number of the alcoholic carbon changes from to +1 to +2 . because of this change, the carbon is oxidized . in below quation.

but some tomes when reaction conditions are changed are are using different reagent like Cr2O7-2 reagent

alcohol changes to acid then carbon oxidation number changes +1 to +3.

Oxidation-Reduction “redox” type reactions are just one of many different forms of a chemical reaction. Combustion reactions fall under the umbrella of redox reactions. Explain what is happening in a redox reaction. What happens to an element that is oxidized? What happens to an element that is reduced? What is an oxidizing agent, and a reducing agent? Finally, assign oxidation numbers and identify what is being oxidized, what is being reduced, and what is the oxidizing and reducing agent for...

Microbial methane oxidation is an important process because it drastically limits the release of this dangerous greenhouse gas. A group of microbiologists used enrichment cultures of archaea from sediments to obtain two isolates. One oxidized CH4 to CO2 using NO3− as an electron acceptor to generate N2. The other isolate reduced Fe(III) to Fe(II) during methane oxidation. If you mixed the two isolates with equal amounts of nitrate and Fe(III), which methane-oxidizing archaeon do you think would grow fastest? Why?

please (TYPE) the answers 1. This week’s oxidation reaction is considered a “Green Chemistry” reaction because of its use of Ozone as the oxidizing agent. In the late 1990s, two chemists, Paul Anastas, and John Warner, co-authored a book regarding how to perform chemical transformations with non-hazardous materials. They created a list of 12 Green Chemistry Principles. Using a textbook or internet, list the 12 principles of Green Chemistry. 2.
