Answer is: the equilibrium concentrations fluorine anion are 0.004 M and lead cation are 0.002 M.<span>
Chemical reaction: PbF</span>₂(aq) → Pb²⁺(aq) + 2F⁻(aq).<span>
Ksp = 3,2·10</span>⁻⁸.
[Pb²⁺] = x.
[F⁻] = 2[Pb²⁺] = 2x<span>
Ksp = [Pb²</span>⁺] ·
[F⁻]².
Ksp = x · 4x².
3,2·10⁻⁸ = 4x³.
x = ∛3,2·10⁻⁸ ÷ 4.
x = [Pb²⁺] = 0,002M = 2·10⁻³ M.
[F⁻] = 2 · 0,002M = 0,004 M = 4·10⁻³ M.

1.429 atm - 1086mmhg
9361 pa-9.36 KPa - 70.21 mmhg
725 mmhg -0.95 atm- 96.26 kpa
calculation
(a) 1 atm = 760 mmhg
1.429 atm = ?
1.429 x760/1 = 1086.34 mm hg
(B) 1 mmhg = 101.325 kpa
? =9361 KPa
9361 x1 /101.25 =70.21 mmhg
760 mm hg= 101.325 KPa
70.21 mm hg=?
70.21 x101.325/760 = 9.36 Kpa
(C ) 1 atm = 760 mmhg
? = 725
= 725 x1/ 760=0.95 atm
1 atm = 101.325 kpa
0.95 =?
0.95 x101.325/1 = 96.26 KPa
A chemical reaction is a process in which one or more substances referred to as reactants are converted into one or more substances referred to as products.
- A chemical reaction can be defined as a chemical process that gives as a result one or more substances referred to as products of that reaction.
- A chemical reaction is catalyzed by specific proteins called enzymes, which are capable of lowering the activation energy of a chemical reaction.
- The most common types of chemical reactions include decomposition, synthesis, single and double replacement.
In conclusion, a chemical reaction is a process in which one or more substances referred to as reactants are converted into one or more substances referred to as products.

An anode is an electrode, it can be a metal or another conductor. in an electrochemical cell that is polarized if an electric current flows into it. Electric current flows opposite to the direction of movement of electrons. In electrochemical processes, both galvanic cells (batteries) and electrolysis cells, anodes undergo oxidation.
In contrast to an Anode, a Cathode is an electrode pole in an electrochemical cell that is polarized if this pole is positively charged (so that an electric current will flow out of it, or the movement of electrons will enter this pole).
In galvanic cells or power plants (batteries), the anode is the negative pole. The electrode will release electrons towards the circuit and hence an electric current flows into this electrode and makes it an anode and negative.
If the system is cooled, more of the products will be formed as the equilibrium shifts to the right.
Explanation:
The reaction is an endothermic reaction which absorbs heat from the environment. This is why we see energy on the reactant side.
This reaction is in equilibrium when energy is absorbed in this manner.
According to Le Chatelier's principle "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
- A change in temperature of an equilibrium system shifts the system to a new equilibrium point.
- The backward reaction is favored by an increase in temperature because heat is absorbed in that step.
- This will eventually lead to the production of more of the product.
- Cooling the system will decrease the temperature and will favor the forward reaction.
- If the system is cooled, more of the products will be formed as the equilibrium shifts to the right.
- More NO gas will be produced in the process.
