These two original review records come from the earlier Chemistry I Chapter 2 draft. The sodium chloride molecular-weight question is absent from the selected edition. The Hydrogen question is an earlier wording and distractor version of selected review question 5. Original prompts, options and answer keys remain unchanged. They are separate earlier-source records and do not increase the primary review question count.
