Which element is found in both potassium chlorate (KClO_3) and zinc nitrate (Zn(NO_3)_2)?

• A. Oxygen
• B. Zinc
• C. Potassium
• D. Chlorine

Answer: (A)

Verified step by step guidance

1. Identify the chemical formulas given: potassium chlorate is \(KClO_3\) and zinc nitrate is \(Zn(NO_3)_2\).
2. List the elements present in potassium chlorate (\(KClO_3\)): potassium (K), chlorine (Cl), and oxygen (O).
3. List the elements present in zinc nitrate (\(Zn(NO_3)_2\)): zinc (Zn), nitrogen (N), and oxygen (O).
4. Compare the elements from both compounds to find which element appears in both lists.
5. Conclude that oxygen (O) is the element found in both potassium chlorate and zinc nitrate.
