Avogadro’s number is derived from the number of carbon-12 atoms in 12.00 grams. In a chemical reaction, 3.0 moles of hydrogen react with 4.0 moles of oxygen to produce water. How many reacting molecules are present when the reaction starts? A.
1.8 x 1024 molecules

B.
6.0 x 1023 molecules

C.
4.2 x 1024 molecules

D.
2.4 x 1024 molecules

explanation:

because dgjpwojefopjwp

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.
