Consider the reaction: 2H2 + O2 2 H2O
If 4.73 moles of H2 reacts, how many moles of O2 also reacts? (Must Show all work and
answer here)

answerlinnaeus;

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.
