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:

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

answer: mole of the gas

answer: mole of the gasexplanation:
