Which of the following equations is balanced?
A) AlBr3 +K → KBr + Al
B) P4 + 6Br2 → 4PBr3
C) 2LİCl + Br2 → LiBr + Cl2
D) AgNO3 + 2Li + 2LİNO3 + Ag

first one is the correct answer

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
