Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Understand the Ionic Charges
- $$S^{2-}$$ has a 2- charge
- V^{5 +} has a 5 + charge
Step 3:: Determine Compound 1 - MgBr_{2}
- Empirical formula: $$MgBr_{2}
- Magnesium will have 1 ion, and bromine will have 2 ions
Step 4:: Determine Compound 2 - MgS
- One $$Mg^{2+}$$ ion balances one $$S^{2-}$$ ion
- Empirical formula: MgS
Step 5:: Determine Compound 3 - VBr_{5}
- One $$V^{5+}$$ ion requires 5 $$Br^{-}$$ ions to balance the charge
- Empirical formula: VBr_{5}
Step 6:: Determine Compound 4 - VS_{2}
- One $$V^{5+}$$ ion requires 2 $$S^{2-}$$ ions to balance the charge
- Empirical formula: VS_{2}
Final Answer
1. MgBr_{2} 2. MgS 3. VBr_{5} 4. VS_{2}
