Position 3 is the answer.
The empirical formula<span> of a chemical compound is the simplest positive integer ratio of atoms present in a compound. Therefore, the correct answer from the choices is the last option. </span><span>C7H14 and C10H20 have the same empirical formula which is CH2. Hope this answers the question.</span>
Explanation:
Species present are
,
and
. Now, we will calculate the number of componenets present as follows.
C = n - E
where, E = number of independent equations
n = number of phases present
Therefore, we will calculate the number of components as follows.
C = 3 - 1
= 2
Since, sodium chloride (NaCl) will tend to form a homogeneous mixture in water. Therefore, phase will be equal to 1.
Therefore, it means that there are two components present in one phase.
"For example; water is a covalent compound which is formed by the covalent bonding between hydrogen and oxygen atoms."
