Explanation:

An apple pie is a mixture whereas lead iodide is a compound. To processes leading to the formation of a mixture and a compound are completely different.

  • A compound is a substance composed of two or more kinds of atoms that are joined together to form a definite matter.
  • The properties of the compound formed differs from that of the constituent atoms.
  • A mixture on the other hand is made up of indefinite compositions.
  • In the case of the apple pie, the parts are not homogeneous in nature.

To produce lead iodide, chemical reactions must take place between atoms.

In the case of  the pie, chemical and physical changes can take place.

Calculate the concentration of buffer components present in 210.00 mL of a buffer solution that contains 0.300 M NH4Cl and 0.300
Lynna [10]

Answer:

[NH3] = 0.270M

[NH4Cl] = 0.327M

Explanation:

The HNO3 will react with the weak base, NH3, as follows:

HNO₃ + NH₃ → NH₄⁺ + NO₃⁻

Initial moles of each specie of the buffer:

NH3 = NH4⁺ 0.210L * (0.300mol/L) = 0.063moles

The moles added of HNO3 = Additional moles of NH4Cl and the moles substracted of NH3:

0.001L * (6mol / L) = 0.006 moles.

After the addition:

Moles NH3 = 0.063mol - 0.006mol = 0.057moles

Moles NH4Cl = 0.063mol + 0.006mol = 0.0069moles

And their concentrations are:

[NH3] = 0.057moles / 0.211L = 0.270M

[NH4Cl] = 0.069moles / 0.211L = 0.327M
