3. (05.02 MC) How many moles are in 25.0 grams of KMnO4? (3 points)
0.124 mol KMnO4
0.158 mol KMnO4
0.199 mol KMnO4
0.316 mol KMnO4

the millers tale is the answer.

clouds form

solid ice forms on leaves.

water droplets form on grass.

it is b that is 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.
