1. How many moles of AgO are in 12.3 g of O 2. How many grams of Aluminium can be recovered from a 54.3 g sample of Al3S3

it should be all of them because it asks if you included all of those in your answer

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.
