A student wants to prepare 100.00 mL of a standard solution. What is the best piece of glassware he should use to ensure he knows the exact concentration of the standard

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

gas

explanation:

smoke is the matter of a gas

i think is conclusions.i think so

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.
