What is the charge of lead in PbO3

+ or - 4

Explanation:

I have attached a periodic tale with ion charges for help :) Pb is located underneatht the + or - 4 charge, so therefore it has a + or - 4 charge. The only time this doens't apply is when you have transitions metals and are given the charge in the equation.

Hope this Helps!

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Green is technically every other color but green but the other wavelengths of the other colors get absorbed by the object and the wavelength of the color green gets reflected
