The chlorine in PbCl2 exists as chloride ions, and the oxidation number of chloride ions is always -1.
-1
The oxidation number of lead (Pb) in the compound PbCl2 has to be what?
+2
To determine the number of atoms of chlorine in 445g of lead chloride (PbCl2), you need to calculate the number of moles of PbCl2 in 445g and then multiply it by the number of chlorine atoms in one PbCl2 molecule. First, calculate the number of moles of PbCl2 using the formula: moles = mass / molar mass. The molar mass of PbCl2 is 278.1 g/mol, so moles = 445g / 278.1 g/mol = 1.6 moles. Since there are two chlorine atoms in one molecule of PbCl2, the total number of chlorine atoms is 2 * 1.6 moles = 3.2 moles of chlorine atoms. To convert moles to atoms, multiply by Avogadro's number. Therefore, there are 3.2 moles * 6.022 x 10^23 atoms/mole = 1.9264 x 10^24 atoms of chlorine in 445g of PbCl2.
In per chloric acid HClO4, the oxidation number of chlorine is +7.

-1. However PbCl is not a compound of lead- PbCl2 and PbCl4 are
This is a anion. chlorine shows +5 oxidation number.
This is a gas compound. Chlorine shows +4 as the oxidation number.
In HgCl2, mercury's oxidation number is 2+ and chlorine's is 1-.
-1 is found in chlorides. But chlorine can have other oxidation numbers up to +7 in its compounds.
