PbO2 is lead(IV) oxide.
‚Black!
First , its NaOCl, with a lowercase L, not an i. There are 12 atoms in 4 formula units of NaOCl.
The ionic chemical formula of lead(IV) oxide is: (Pb)4+ + 2 O-.
Pb + PbO2 + H2SO4 --> PbSO4 + H2O
Lead Dioxide or Lead IV Oxide
0.0362 x 1911.9 g = 69.2 g NaOCl (to 3 significant figures based on 0.0362).
3.62 percent by mass means that there are 3.62 g NaOCl per every 100 g of solution. So, to find grams in 1911.9 g solution, just multiply ...3.62 g NaOCl/100 g soln x 1911.9 g soln = 69.2 g NaOCl
by reacting the brome in the the sodium chloride: Br + NaCl----- BrNa + cL---------cl+naocl= naocl
acetone
An ionic bond.
