Which of these is a property of a substance that is composed of atoms that are held together by metallic bonds? a: it has low melting pointb: it can be flattened and bentc: it cannot be shaped into wiresd: it does not conduct electricity

The answer to your question is letter B: it can be flattened and bent.

Explanation:

Metals have a lot of properties because of their bonds, these properties are:

- They have high melting and boiling points

- They can be flattened and bent (malleability and ductility)

- They can be shaped into wires

- They can conduct heat and electricity

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 .
