Describe the ways in which ionic compound nomenclature differs from covalent compound nomenclature
Igoryamba

Answer:

Ionic compound are when electrons are given to another element, making one atom positive and the other negative, so they attract. Covalent compound is when both atoms share electrons with each other.

The temperature of evaporation is much higher for water than for alcohol. Without knowing more about the chemistry of alcohol, w
Valentin [98]

Answer:

Fewer hydrogen bonds form between alcohol molecules. As a result, less heat is needed for alcohol molecules to break away from solution and enter the air.

Explanation:

Hydrogen bonding is a kind of intermolecular interaction that occurs when hydrogen is bonded to a highly electronegative atom.

Both water and alcohols exhibit hydrogen bonding. However, alcohols exhibit fewer hydrogen bonds than water.

As a result of this, the temperature of evaporation is much higher for water than for alcohol because hydrogen bonds hold water molecules more closely than alcohol molecules are held.

What type(s) of bonding would be expected for each of the following materials: brass (a copper-zinc alloy), rubber, barium sulfi
mr_godi [17]

The force of attraction that results in holding of atoms or ions together in a molecule or crystal is said be bonding.  Bond formation can take place by either attraction or transfer of electrons. There are single, double, and triple bonds.  There are many types of bonding namely:

Covalent (sharing of electrons takes place).

Ionic (transfer of electrons takes place).

Metallic (ionized atoms of metals and the sea of electrons around them).

  • Brass (a copper-zinc alloy)

Brass is an alloy of metal that is copper and zinc. Hence, the metallic bonding is present in the brass.

  • Rubber

It is a polymer whose monomer unit is isoprene, which is a covalent compound. The isoprene units are attached in repeated units to form rubber by covalent bonding.

  • Barium sulfide (BaS)

Due to the large electronegativity difference between barium and sulfur, barium sulfide is an ionic compound. Thus, ionic bonding is present in barium sulfide.

  • Solid xenon

Only xenon atoms are present in solid xenon which are interacted by weak Van der Waal's interactions.

  • Bronze

Bronze is an alloy of metal that is copper and tin. Hence, the metallic bonding is present in the brass.

  • Nylon

It is a polymer whose monomer unit is caprolactam, which is a covalent compound. The caprolactam units are attached in repeated units to form nylon by covalent bonding.

  • Aluminum phosphide (AlP)

Aluminum phosphide is a covalent compound and thus involves covalent bonding.

Why does aluminium oxide (Al2O3) have a higher melting point than sodium oxide (Na2O)?
Lilit [14]

Al2O3 has a higher melting point than Na2O. This is because the ionic bond between Al3+ ions and O2- ions is stronger than that between Na+ and O2-. The charge on the Al3+ ion is larger than that of the Na+ ion
