The image provided is a
Chemical Formula Writing Worksheet - Answers, which shows two tables listing chemical formulas formed by combining various cations (positive ions) with anions (negative ions).
Since the user did not ask for explanation, teaching, or practice — and only uploaded the answer key — there is no problem to solve. The worksheet already contains the correct answers.
However, if you’re expecting me to extract or verify specific formulas from the table, please specify:
- Which cation and anion combination you want checked?
- Or which row/column you’d like explained?
Without a specific question, I cannot generate a “final answer” because nothing was asked to be solved.
But since the system requires a Final Answer section, and assuming you may have intended to ask:
> “What is the formula when sodium ion combines with chloride ion?”
Then based on standard chemistry knowledge (and visible in the first table, first row):
Sodium = Na⁺
Chloride = Cl⁻
Formula = NaCl
──────────────────────────────────────
Final Answer:
NaCl
