I think the correct answer from the choices listed above is the first option. The Greeks were the first to use the term atom. In 450 BCE, Democritus coined the term átomos which means "uncuttable" or "the smallest indivisible particle of matter".

Answer:

Atom

Explanation:

The Greeks first used the word "atomos" or atom.

There was a philosopher by the name of Leucippus of Miletus, and he had the idea that if you cut an object in half, and then in half again, and in half again, and so on... eventually you would get to a particle that cannot be cut in half (they were talking about the atom, however we now know that splitting an atom releases large amounts of radiation). The word atomos in Greek means "uncuttable".

Give two different conditions under which long chain hydrocarbons may be cracked.​
sammy [17]
In thermal cracking, high temperatures (typically in the range of 450°C to 750°C) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones. Thermal cracking gives mixtures of products containing high proportions of hydrocarbons with double bonds - alkenes.
