Answer:
Electrical conductivity in metals is a result of the movement of electrically charged particles. Because valence electrons are free to move, they can travel through the lattice that forms the physical structure of a metal.

Answer:
Explanation:
The law of multiple proportions say that two elements, A and B, are able to combine with each other to form distinct compounds, the different masses of B that bind to a certain mass of A, are in relation of integers and simple numbers.
2SO₂ → S₂ + 2O₂
Mass S₂=2 . 32g= 64g
Mass 2O₂=4 . 16g=64g
∴ 64/64=1 ⇒ One produced 1.002 g S for every gram of O, the relation is 1:1
2SO₃ → S₂ + 3O₂
Mass S₂=2 . 32g= 64g
Mass 3O₂=6 . 16g=96g
∴ 64/96= 2/3 ⇒ It is produced 0.668 g S for every gram of O, the relation is 2:3.
To sum up, these results are consistent with the law of multiple proportions because the results are integers and simple numbers.
