The ether layer with a dissolved yellow compound is on top and an aqueous layer is at the bottom. Apple, banana, carrot, and lettuce extraction using acetone, water, and dichloromethane. Lower layer is the organic layer.
The Ozone Layer The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3).This layer absorbs 97-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth.zone layer thickness is expressed in terms of Dobson units, which measure what its physical thickness would be if compressed in the Earth's atmosphere. In those terms, it's very thin indeed. A normal range is 300 to 500 Dobson units, which translates to an eighth of an inch-basically two stacked pennies.
