the two species of pine trees have more characteristics in common than the pine trees and the palm trees
none of the tree species have any characteristics in common

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

the answer is barium and copper bromide

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.
