freezing and condensation

Explanation:

The motion of the atoms decreases during freezing and condensation. These are phase changes that increases the molecular attraction between particles and forces them to come closer.

Freezing is a phase change from liquid to solid. It is usually achieved by removing heat from a substance and cooling it.

Condensation is a phase change from gases to liquid. .

Gases have the greatest motion because they have little to no attractive forces between them.

Phase changes from gas to solid to liquid generally reduces the motion of the atoms.

oxygen is a common oxidizing agent in nature. what change in the oxidation number of oxygen must occur if it is to be an oxidizi
Minchanka [31]

Answer is: the oxidation number of oxygen must decrease.

Oxidizing agent is element (substance) that gain electrons in chemical reaction.

For example, balanced chemical reaction: C + O₂ → CO₂.

Oxygen change oxidation number from 0 to oxidation number -2 (reduction) and carbon change from 0 to +4 (oxidation)

Ionic compounds are held together with ionic bonds between ions. The ions are formed when valence electrons are
Elza [17]

Answer: Electrovalent bonds are produced when electrons are transferred from atoms of one element to atoms of another element, producing positive and negative ions. The bond which is formed by the transfer of electrons between the atoms is called electrovalent bond or ionic bond. Electrovalent bonds are only formed between metals and non-metals. Electrovalent bonds are not formed between two non-metals.

In simple words electrovalent bond involves the transference of a certain number of electrons to another dissimilar atom which has a tendency to gain electrons so that both acquire stable inert gas configurations. The electrostatic attraction always tends to decrease the potential energy. Hence, the potential energy of the system is much less than it was before the formation of an ionic bond.

Explanation: An Ionic bond is the bond formed by the complete transfer of valence electron to attain stability.

This type of bonding leads to the formation of two oppositely charged ions – positive ion known as cations and negative ions are known as anions.

The presence of two oppositely charged ions results in a strong attractive force between them. This force is an ionic or electrovalent bond.

Ionic bonds form between atoms with large differences in electronegativity, whereas covalent bonds formed between atoms with smaller differences in electronegativity.

The compound formed by the electrostatic attraction of positive and negative ions is called an ionic compound.
