Answer:
In the kinetic molecular theory of gas behavior; the assumption is made that gas molecules move with a kinetic energy equal to their centigrade temperature_ move rapidly in random directions: are close together in their container which exerts pressure_ are attracted to each other by strong forces.

Answer:
Calculate the entropy change for the reaction: Fe2O3(s) + 2Al(s) -> Al2O3(s) + 2Fe(s) Entropy data: Fe2O3(s): 90 J/K mol Al(s): 28.3 J/K mol Al2O3(s): 51 J/K mol Fe(s): 27.2 J/K mol

Explanation:
The given cation:
(Rf₂Al₂F₃)³⁺
The oxidation number gives the extent to which a specie is oxidized in a reaction.
This number is assigned based on some rules:
- Elements in combined state whose atoms combines with themselves have an oxidation number of zero.
- The charge carried on simple ions gives their oxidation number.
- Algebraic sum of all the oxidation numbers of atoms in neutral compound is zero. In an ion with more than one kind of atom, the charge on it is the oxidation number.
for the specie given;
Known:
oxidation number of Al = +3
F = -1
charge = +3
let the oxidation number of Rf = k
2k + 2(3) + 3(-1) = +3
2k + 6 - 3 = 3
2k = 0
k = 0
The oxidation state of rutherfodium is 0
