Problem 3

Why might the expression "1 mol of chlorine" be confusing? What change would remove any uncertainty? For what other elements might a similar confusion exist? Why?

Answer

Chlorine can exist as either an atom (Cl) or a molecule (Cl2). To remove uncertainty, the formula should be used rather than the name. A similar confusion exists with hydrogen, nitrogen, oxygen, fluorine, bromine, and iodine as they all exist as diatomic molecules.

if you were to say that you're using one mole of chlorine, this can be confusing because chlorine exists in two forms as an Adam or as what's called a die atomic molecule. The Adam is the symbol found on the periodic table, or C L. The diatonic molecule is C L two or two Koreans, and in most chemical reactions, C L two is used rather than C L. There are a total of seven elements that in nature exists is die atomic molecules. Hydrogen exist is H two nitrogen and to oxygen is 02 Floren. As we mentioned chlorine, Breault, main and iodine. These are examples of the elements that exist as die atomic molecules to avoid confusion. That's why you should use the formula rather than the word or the name of the element.
