Acetone and sodium chloride both have a similar mass. Explain why their other properties differ. Property Acetone Sodium Chloride Formula C3H6O NaCl Melting point â’94°C 801°C State at room temperature Liquid Solid Electrical conductivity Low High Which statements are true regarding these two compounds? Check all that apply. Acetone is a covalent compound, while sodium chloride is an ionic compound. Ionic compounds conduct electricity well in their solid (pure) form. Covalent compounds have weak attractions between molecules, resulting in low melting points.

Answer 1

Acetone and sodium chloride differ due to acetone's covalent bonding with weaker intermolecular forces and sodium chloride's ionic bonding with strong ionic bonds, leading to higher melting points for NaCl and differing electrical conductivity properties.

Step-by-step explanation:

Acetone and sodium chloride may have a similar mass but they have vastly different properties due to the nature of their chemical bonding and structure.

While acetone is a covalent compound with individual molecules held together by weaker intermolecular forces, sodium chloride is an ionic compound composed of cations (Na+) and anions (Cl-) arranged in a crystalline lattice with strong ionic bonds.

These differences lead to sodium chloride having a higher melting point and being electrically conductive when molten, since ionic compounds can conduct electricity due to the free movement of ions.

However, in the solid state, ions in ionic compounds are immobile, resulting in no electrical conductivity.

On the other hand, covalent compounds like acetone typically have lower melting points owing to the weaker attractions between molecules and do not conduct electricity due to the lack of free ions or charge carriers.

Answer 2

Acetone and sodium chloride have similar mass but differ in other properties due to their different chemical compositions and types of bonding. Acetone is a covalent compound with weak intermolecular forces, resulting in a low melting point and low electrical conductivity. Sodium chloride is an ionic compound with strong electrostatic attractions, resulting in a high melting point and high electrical conductivity.

Step-by-step explanation:

Acetone and sodium chloride have similar mass but differ in other properties due to their different chemical compositions and types of bonding.

Acetone (C3H6O) is a covalent compound that consists of individual molecules held together by weak intermolecular forces. These weak attractions between molecules result in a low melting point and liquid state at room temperature. Acetone has low electrical conductivity because covalent compounds do not dissociate into ions in solution.

Sodium chloride (NaCl), on the other hand, is an ionic compound composed of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-). The strong electrostatic attractions between these ions form a crystal lattice structure, resulting in a high melting point and a solid state at room temperature. Ionic compounds like sodium chloride conduct electricity well in their solid form because their ions can move freely and carry electric charges.
