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!
All alkail metals react with halogens vigorously to produce salt. The alkali metal would loose an electron to form and ion with the halogen
Answer:
Energy can neither be created nor destroyed, but it does change its form. And not all forms of energy are usable and it gets dissipated as heat energy and sound energy. The energy that is wasted cannot be recovered.
Answer:
1. Mountain ranges
2.
3.pacific ocean ??
4.tempature
I'm not really sure on 2 bit trying to help you :)
Larger molecules experience larger dispersion forces due to more distance of valance of electrons from the nucleus.
<h2>Cause of stronger dispersion force
</h2>
Larger atoms and molecules have stronger dispersion forces than smaller atoms and molecules because in a larger atom or molecule, the valence electrons are present farther from the nuclei than in a smaller molecule.
They are less tightly held to the nuclear charge present in the nucleus and can easily form temporary dipoles so we can conclude that larger molecules experience larger dispersion forces due to more distance of valance of electrons from the nucleus.
