Depending on the conditions, manganese (Mn) can exhibit different crystal structures. Under certain conditions, a sample of Mn crystallizes in a cubic crystal lattice with a density of 6.345 g/cm3 and a cell edge length of 386.0 pm. What is the crystal structure of Mn under these conditions

pie chart because it is in percents ( % )

50.23 i believe is correct but don't quote me on that.

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.
