Explanation:

Non-metals have a strong attraction for shared electrons as there is deficiency of electrons in non-metals. Thus, in order to complete their octet they tend to develop attraction for shared electrons if the combining atom does not have excess of electrons to donate.

A substance held together by an ionic bond is known as ionic substance because an ionic bond can only be formed by transfer of electrons.

Metals have a lower attraction for shared electrons because metals contain excess of electrons. Thus, they did not have strong attraction for electrons.

A triple bond is formed when three pairs of electrons are being shared between two atoms. Each pair of electron contains a total of 2 electrons.

An ionic bond is formed when electrons are transferred from one atom to another.

A covalent bond is formed when there is sharing of electrons between 2 atoms. Non-metals are deficient of electrons as compared to metals. Thus, 2 non-metals when combine together then it results in the formation of a covalent bond as there is sharing of electrons.

An ionic bond forms when there is transfer of electrons from one atom to another. An atom with excess of electrons can easily donate its electrons to an electron deficient atom. Therefore, metals and non-metals  will form ionic bonds.

A substance held together by covalent bonds is known as a molecular substance. In molecular substance two atoms are joined together by sharing of electrons that is through covalent bonds.

Therefore, all the points are matched as follows.

d is

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
