i If a chemical system is at equilibrium, any change in the system will always result in an increase of which of the following?

1.The reaction that opposes the change

2. The concentration of the product

3. The concentration of the reactants

4. The temperature of the system​

Answers

Answer 1

Answer:

1.The reaction that opposes the change

Explanation:

Consider the reaction;

A + B ⇄ C + D

If a constraint such as a change in temperature, pressure or volume is imposed on this chemical system in dynamic equilibrium, the equilibrium position will shift so as to annul the constraint.

This shift in the equilibrium position will favour either the forward or reverse reaction depending on the type of constraint imposed on the system.

Hence, If a chemical system is at equilibrium, any change in the system will always result in an increase of the reaction that opposes the change.

We want to write the formulas of different binary ionic compounds. to do so, we need to consider the octet's rule.

What is the octet's rule?

The octet's rule establishes that atoms will lose, gain or share electrons to achieve the electron configuration of the nearest noble gas (8 valence electrons except for He with 2).

a. potassium and iodine

K has 1 valence electron so it will lose 1 electron to form K⁺. I has 7 valence electrons so it will gain 1 electron to form I⁻. The neutral compound between K⁺ and I⁻ is KI.

b. magnesium and chlorine

Mg has 2 valence electrons so it will lose 2 electrons to form Mg⁺². Cl has 7 valence electrons so it will gain 1 electron to form Cl⁻. The neutral compound between Mg⁺²⁺ and Cl⁻ is MgCl₂.

c. sodium and sulfur

Na has 1 valence electron so it will lose 1 electron to form Na⁺. S has 6 valence electrons so it will gain 2 electrons to form S⁻². The neutral compound between Na⁺ and S⁻² is Na₂S.

d. aluminum and sulfur

Al has 3 valence electrons so it will lose 3 electrons to form Al³⁺. S has 6 valence electrons so it will gain 2 electrons to form S⁻². The neutral compound between Al³⁺ and S⁻² is Al₂S₃.

e. aluminum and nitrogen

Al has 3 valence electrons so it will lose 3 electrons to form Al³⁺. N has 5 valence electrons so it will gain 3 electrons to form N³⁻. The neutral compound between Al³⁺ and N³⁻ is AlN.
