True or false? two or more atoms bonded together always form a compound.

The given statement is false.

Explanation:

When an element chemically combines with another element then it results into the formation of a molecule or a compound.

A compound is defined as the substance in which different elements are chemically combined together in a fixed ratio by mass.

For example, is a compound and elements are present in 1:4 ratio.

A compound can be divided into its constituent or simpler substances by chemical means.

And, a molecule is defined as the substance in which two or more same type of elements chemically combine together in a fixed ratio by mass.

For example, , etc are molecules.

Therefore, we can conclude that the statement two or more atoms bonded together always form a compound, is false.

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 .
