Hydrogen exists in three isotopes, H1, H2, and H3. the average atomic mass of hydron is 1.008 amu. which of these three is most abundant? how do you know

Explanation:

everything can be found in the picture above

Hope this helps

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.
