consider this reaction involving an unknown element x.
f2 + 2 xbr — br, + 2 xf
when 3.200 g of xbr reacts, 1.362 g of br, is produced.
calculate the molar mass of x, and then identify its element symbol.
molar mass of x:
g/mol
element symbol for x:

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

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.
