The following set of solutions are prepared by dissolving the requisite amount of solute in water to obtain the desired concentrations. the pressure of the system is then manipulated such that movement is from the solution listed first to the solution listed second. classify each set of solutions based on the movement of solvent from the first solution listed to the second solution listed as osmosis or reverse osmosis. 1. 4.2 m hno3 to 2.4 m hno3 2. 0.4 m nacl to 0.8 m nacl 3. 1 m koh to 2 m koh 4. 0.6 m kcl to 0.3 m kcl 5. 1 m ch3cooh to 0.4 m ch3cooh 6. 0.01 m sucrose to 1 m sucrose

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.

sup bro, im dumb, but this is what i found xd

"the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface"
