Oxidation state of Pb in PbO2 is +4.
Oxidation state of Pb in PbCl2 is +2.
Oxidation state of Pb in Pb2O is +1.
Oxidation state of Pb in Pb4O3 is +6/4.
Hence option A. PbO2 is correct.
Hope this helps, have a nice day!
Answer: 0.0250
Explanation: 10 X 0.0750 = .75
.75 / 30 = 0.0250 M
Its true, By definition, an atom is electrically neutral<span> it has the same number of protons as it does electrons, plus some number of neutrons depending on the isotope</span>
The soda can from the car will lose CO2 more quickly. This is because of the kinetic energy and behavior of gas molecules under different temperatures. CO2 is more soluble in cold temperatures than hot. Cold temperatures minimize the kinetic energy of gas molecules; thus, preventing the gas from escaping the soda. This is why soda that comes from the refrigerator has more fizz or spirit than soda at room temperature.
Do you mean 4+7 if yes it’s 11
