1. Using the following equation: How many moles of lithium nitrate, LINO3, will be needed to make 11.4
moles of lithium sulfate, Li2SO4?
Pb(SO4)2
+
4 LINO3
→
Pb(NO3)4
+
2 Li2SO4

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: )
