A molecular covalent substance (such as co2) has a low melting point because the covalent bonds that hold the molecules together
Leona [35]

A molecular covalent substance (such as co2) has a low melting point because the covalent bonds that hold the molecules together are weak and do not require much energy to break:- False.

What are covalent bonds ?

An electron transfer that leads to the formation of electron pairs between atoms is known as a covalent bond. When atoms share electrons, a stable balance of the repulsive and attractive forces among them is known as covalent bonding. These electron pairs are also known as bonds or shared pairs.

It is a molecular compound, which is a mixture of at least two atoms—the smallest building blocks of matter—joined by a covalent bond. These atoms are joined by a covalent bond, which is formed when electrons are shared.

Answer:

Gas to Solid

Explanation:

A condensation reaction goes from gas to solid

Condensation is a physical change which alters the physical properties of matter particularly the form and state. In a condensation reaction, a gas goes from solid to liquid.

It is the inverse of the sublimation reaction.

  • It involves the loss in energy by a gas.
  • When gases lose energy, they become pulled together by attractive forces.
  • This changes their state to solid with enough loss in energy.
