Consider the following reaction:
4P +502 P4010
The percent yield of P4010 when 6.20 g of phosphorus burns in
excess oxygen is 67.0 %.What is the actual yield of P4010?
(Molar mass of P = 31.0 g/mol, molar mass of P4010 = 284
g/mol) (Round your answer 3 significant figures e. g. 5.62)
grams

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

answerto predict;

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.
