PLEASE HELP ASAP ;( make sure you fill out the table carefully, it is important to recognize that the first four columns are b) for the elements and/or particles at the beginning of the reaction. the four columns on the right are for the final products. be sure your initial total mass is equal to the final total mass, as per the law of conservation of energy.
BASICALLY IF YOU HAVE THIS DONE I NEED HELP W THE ENTIRE PROJECT..

the answer is option a.

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.
