PLEASE HURRY: Which of the following compounds would dissociate or separate when put in water?

KCl
C6H12O6
N2O5
CO2

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

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.
