A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation colum

Answer:

             Protons: 19

             Neutrons: 25

             Electrons: 19

Explanation:

Protons:

                   The atomic number determines the number of protons in an atom. Consequently, with Potassium's atomic number being 19, it contains 19 protons.

Neutrons:

                   The formula to find neutrons is:

                           # of Neutrons  =  Atomic Mass - # of Protons

Given:

                                Atomic Mass  =  43

                                # of Protons  =  19

Thus,

                                # of Neutrons  =  43 - 19

                                # of Neutrons  =  24

Electrons:

                                   In a neutral atom, the quantity of electrons matches that of protons. Therefore, a neutral Potassium atom with 19 protons must equally have 19 electrons.

Students dealing with ionic bonds comprehend better how to convey what the model should showcase.

Explanation:

• Upon dissolving ionic compounds in water, the compounds separate into their constituent ions via a process called dissociation.
• The ions become attracted to water molecules, which carry a polar charge.
• If the pull between the ions and the water molecules is strong enough to disband the ionic bonds, the compound dissolves.
• The ions disperse in the solution, each surrounded by water molecules to inhibit reattachment.
• The ionic solution forms an electrolyte, allowing it to conduct electricity.
• In contrast, while covalent compounds do dissolve in water, they separate into molecules, not individual atoms.
• Water acts as a polar solvent, yet covalent compounds are generally nonpolar.
• This implies that covalent compounds often do not dissolve in water and instead form a distinct layer on top of the water.
