CHEM120 Week 5 Concepts: Redox and Organic Chemistry – Download For Revision And Score An A+ OXIDATION-REDUCTION Reduction and oxidation are intertwined concepts that are important to understand ing some of the most important chemical reactions in the human body. In this lesson, we will explore the relationship between these terms and the how to identify what chemicals in a reduction/oxidation reaction (redox reaction) are playing which parts. 1. Redox reactions involve a transfer of: ▪ Nucl...

CHEM120 Week 5 Discussion: Organic Chemistry – Dichloro-diphenyl-trichloroethane (Option 1) Week 5 Discussion: Organic Chemistry Option 1: A growing concern in agricultural and food chemistry is the presence of residues in food. We use many forms of organic chemicals in agriculture and food chemistry and there is a growing concern as to how safe these materials are. The organic compound that I choose for option one is DDT also known as Dichloro- diphenyl-trichloroethane. DDT was the primary ch...
