Answer is: Ksp = 4s³.
Balanced chemical reaction (dissociation) of strontium hydroxide:
Sr(OH)₂(s) → Sr²⁺(aq) + 2OH⁻(aq).
Ksp(Sr(OH)₂) = [Sr²⁺]·[OH⁻]².<span>
[</span>Sr²⁺] = s.<span>
[</span>OH⁻] = [Sr²⁺] = 2s<span>
Ksp = (2s)² · x = 4s³.
Ksp is the solubility product constant for a solid substance dissolving in an aqueous solution.
[</span>Sr²⁺] is equilibrium concentration of iumcations.<span>
[</span>OH⁻] is equilibrium concentration of hydroxide anions.

Draw a mechanism for the reaction of water with formic acid. In the box to the left, draw any necessary curved arrows. Show the
dsp73

Answer:

See explanation

Explanation:

When water reacts with formic acid, The following equilibrium is set up;

HCOOH(aq) + H20(l) ⇄ HCOO-(aq) + H30+(aq)

This is because, the water abstracts a proton from formic acid to form its conjugate base, formate ion.

At equilibrium,  the forward is favored.

The synthesis of CH3OH from CO and H2 is represented by the equation below.
sergij07 [2.7K]

Answer: Option (b) is the correct answer.

Explanation:

In a chemical reaction, the bonds between the reactant molecules tend to break leading to the formation of new bonds to produce products.

So, in order to break the bonds between the reactant molecules, energy is required to overcome the attraction between the atoms.

To form new bonds, energy gets released when two atoms come closer to each other.  Hence, formation of bond releases energy.

As in the given reaction it is shown that \Delta H < 0, that is, enthalpy change is negative. Hence, energy is released as it is an exothermic process.

Thus, we can conclude that the statement energy released as the bonds in the reactants is broken is greater than the energy absorbed as the bonds in the products are formed, is true about the bond energies in this reaction.
