ancient Greece of 400 B.C.there was a brilliant philosopher named Democritus, and he proposed the Greek word atomos, which means uncuttable. And so as he explained, all matter was eventually reducible to discrete, small particles or atomos.
The equilibrium shift is if the HCl concentration is increased in the product.
Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
<h3>What is the effect of concentration on equilibrium?</h3>
If the concentration of a substance is changed, then the equilibrium will shift in such a way that it minimizes the effect of change that occurs. If we increase the concentration of a reactant, then the equilibrium will shift to minimize the changes in the direction of the reaction which uses the reactants, so that the reactant concentration decreases.
<h3>Factors affecting the concentration of the reaction</h3>
- The temperature: As we increase the temperature, the average speed of the reactant molecules also increases. As many molecules move faster, a large number of molecules moving fast enough to react increases, making the faster formation of products.
- pressure
- and concentration of the system is the factors that affect equilibrium.
Thus, we concluded that with an increase in the concentration of reactant equilibrium shifts forward.

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

Answer:
Here are some of the differences between a mixture of iron and sulfur, and iron sulfide: the mixture can contain more or less iron, but iron sulfide always contains equal amounts of iron and sulfur. the iron and sulfur atoms are not joined together in the mixture, but they are joined together in iron sulfide.
Explanation:
