Depletion of the Ozone Layer Essay Preview: Depletion of the Ozone Layer Report this essay The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What.
Hydrogen Peroxide Chemical Reaction Rate Discussion: In this experiment, the rate of reaction will be investigated. When hydrogen peroxide is added to a solution of potassium iodide, the iodide ions are slowly oxidized according to the equation: This reaction can be modified by the introduction of a small amount of S2O32- (aq) and starch indicator..
Hydration of Cyclohexene Lauryn TonouDate: 04/13/2015Partner’s name: Dolly, StarrHydration of cyclohexenePurpose:The purpose of this lab is to converse cyclohexene to cyclohexanol by hydration.Introduction:In this lab, the synthesis of cyclohexene from cyclohexanol will be performed by the dehydration of an alcohol. This is an elimination reaction, in which two groups, or atoms, will be removed from the.
