OPTION B
Explanation:
Nuclear "fission" is the breakdown of the nucleus of a radioactive element into two or more nuclei accompanied by the release of energy. I guess that pretty much explains it.
Answer:
Single-Replacement Reaction
General Formulas and Concepts:
<u>Chemistry - Reactions</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define RxN</u>
Mg + H₂SO₄ → MgSO₄ + H₂
<u>Step 2: Identify RxN</u>
Mg + H₂SO₄ → MgSO₄ + H₂
Single-Replacement Reaction A + BC → AB + C
- A = Mg
- BC = H₂SO₄
- AB = MgSO₄
- C = H₂
