2Pb²⁺ + O2 -----> 2Pb⁴⁺ + 2O²⁻
(Pb²⁺-2e ----> Pb⁴⁺) *2
O2 +4e ----->2O²⁻
add 2 last equations
2Pb²⁺-4e+ O2 +4e ----> 2Pb⁴⁺+ 2O²⁻
2Pb²⁺ + O2 -----> 2Pb⁴⁺ + 2O²⁻
Answer:
Thus, molar volumes of the liquids are expected to be closer to those in the "solid state."
Explanation:
Anything which occupies mass is known as the matter and we know that matter is existed in three states i.e. solid, liquid and gas. The atoms in the solid are closely packed and therefore, they posses very less kinetic energy. The atoms in liquid state are less closely packed and possess more kinetic energy in comparison to the solid state. The atoms in the gaseous state are loose and possess maximum kinetic energy. The molar volume is the volume occupied by 1 mole of a substance. Solid being compressed will have lesser volume in comparison to the liquid and liquid will have lesser volume in comparison to the gas.
In the solid state, it is expected that the amount of empty space is less than that of the gaseous state, and molar volumes are influenced by molecular characteristics. Thus, solid state molar volumes are not similar to those in the gaseous state. When, comparing empty space in the liquid state, it is expected that space in the liquid phases is less than space in the gaseous phase and equivalent to space to the solid state. Thus, molar volumes of the liquids are expected to be closer to those in the solid state.

A. law
Because here’s the definition of law
laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases across all fields of natural science.
Metals are all in the center of the periodic table and are all made up of metals
