A different student is given a 10.0 g sample labeled CaBr2 that may contain an inert impurity. Identify a quantity from the result of laboratory analysis that the student could use to determine whether the sample was pure

Hi wanna be friends

Explanation:

Yes or no my name arrianna but you can give me a nickname if you want to

b. atoms in metallic solids are not arranged in a regular pattern

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.
