The atoms on the products side are bonded into different molecules from the atoms on the reactants side is the chemical changes occured.

Explanation:

The reaction commences when the compounds on the reactant side are ready to react to give the product.
The reaction initiated by the transfer of electrons and molecules from the reactants to give the combined product of both the reactants.
It is a process on which there will be rearrangement in the structure of molecules of a substance from its physical for more chemical form.
In the above picture it shown that the red molecules combined with the white molecules additionally and changed the structure.

In the reaction

Sedbober [7]

Answer:

rate = [NO]²[O2]

Explanation:

The rate law for the reaction:

2 NO(g) + O2(g) → 2 NO2(g)

Is expressed in terms of reactants as follows:

rate = [NO]ⁿ[O2]ˣ

Where n and x are the coefficients of the rate law.

If [NO] is doubled, the rate increased 4 times. That is only possible if:

rate = [NO]²[O2]ˣ

Now, as [NO] is doubled and increased the rate 4 times, and [NO] + [O2] when doubled increased the rate 8 times, doubled [O2] implies increased the rate 2 times. That is only possible is:

When 15.0 mL of a 6.42×10-4 M sodium sulfide solution is combined with 25.0 mL of a 2.39×10-4 M manganese(II) acetate solution d

Answer:

Q = 3.59x10⁻⁸

Yes, precipitate is formed.

Explanation:

The reaction of Na₂S with Mn(CH₃COO)₂ is:

Na₂S(aq) + Mn(CH₃COO)₂(aq) ⇄ MnS(s) + 2 Na(CH₃COO)(aq).

The solubility product of the precipitate produced, MnS, is:

MnS(s) ⇄ Mn²⁺(aq) + S²⁻(aq)

And Ksp is:

Ksp = 1x10⁻¹¹= [Mn²⁺] [S²⁻]

Molar concentration of both ions is:

[Mn²⁺] = 0.015Lₓ (6.42x10⁻⁴mol / L) / (0.015 + 0.025)L = 2.41x10⁻⁴M

[S²⁻] = 0.025Lₓ (2.39x10⁻⁴mol / L) / (0.015 + 0.025)L = 1.49x10⁻⁴M

Reaction quotient under these concentrations is:

Q = [2.41x10⁻⁴M] [1.49x10⁻⁴M]

Q = 3.59x10⁻⁸

As Q > Ksp, the equilibrium will shift to the left producing MnS(s) the precipitate
