phosphorus burns in the limited supply of air to form phosphorus(iii)oxide, P4O6 and in unlimited supply of air to form phosphorus(v)oxide P4O10. If 3.3g of phosphorus(iii)oxide is formed what mass of oxygen from air is used

ugh fiel iente of insistí is did kiwis jaj

what is the question here. i think you messed up.

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.
