Concept explainers
Interpretation:
The meaning of the statement, “the smallest particles unique to an element may be atoms or molecules” is to be interpreted.
Concept introduction:
An element can be defined as the basic type of matter which is composed of only one kind of atom. An atom is the fundamental unit of matter and hence an element cannot be broken down further into a simpler form.
Atoms are tiny particles which make up every matter in the universe. Every matter in the universe is composed of atoms.
A molecule can be defined as the smallest unit of a chemical compound. Molecules are made up of two or more same or different atoms. Molecules can further be classified as homogeneous or heterogeneous. Homogeneous molecules are composed of the same kind of atoms whereas heterogeneous molecules are composed of atoms of more than one kind.

- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
