Describe the three-step Bayer process, by which aluminum oxide is purified from bauxite and include the three chemical equations for each step. lIdentify the type of chemical reaction each of these equations are. What happens next to the aluminum oxide?

these nuts

i think that the answer is c

c) should be the answer.

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.
