HELP!! Due Tomorrow! Given the balanced equation below for the highly exothermic reaction of aluminum with oxygen to form aluminum oxide: What is the value of ΔH when 1.00 mol of aluminum reacts? What is the value of ΔH when 5.23 g of aluminum reacts? What is the value of ΔH when 6.17 L of oxygen gas at STP reacts with excess aluminum? A certain reaction releases 6881 kJ of heat. What mass of aluminum oxide was produced in the reaction?

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

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.
