what is the comound name for the formula PbCl2?


Sagot :

Lead (II) chloride 
......................................
Chlorine has a charge of -1 and lead can have a charge of +2 or +4
The charges need to be balanced, so if lead was +4 then the equation would be PbCl4, because chlorine needs 4 atoms to balance out lead.  Because it was Cl2, we know it was lead (II)
