How many moles of CH4 will be burned to produce 10 moles of CO2? pls help its for my chem hw i dont want to fail

idk what is it? is this a question that you know the answer or u dont

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.

i think tornado but not 100%
