Element which possess different number of "Neutrons" in different situations could be an isotope of the atom
Ex. - 17 Cl 34, 17 Cl 35, 17 Cl 36
They all the isotopes.
Hope this helps!

A proper chemical storage includes the following;
-
Management – this includes of managing the
storage area of the chemical and how they are stored base on their difference
and property
-
Compliance – this is the action needed in means
of having to be able to understand the properties of the chemical in order to
know what action is needed to engaged on
Answer:
38.0 g C2F3Cl3) / (187.3756 g C2F3Cl3/mol) x (3 mol Cl / 1 mol C2F3Cl3) x (35.4532 g Cl/mol) =
21.6 g Cl in C2F3Cl3
For this case, Only 1 isotope would be present, i.e. the principal element with mass M=13 and then one isotope at mass M+2. <span>We are assuming that the principal element is the one that is the lowest mass - by definition, an isotope is one where there are additional neutrons - hence the mass increases, but the proton count is the same.
