write the empirical formula for at least four ionic compounds that could be formed from the following ions: $nh_{4}^{+}, fe^{2 + }, ch_{3}co_{2}^{-}, clo_{3}^{-}$

Answer

Answer:

  1. $\ce{NH4CH3CO2}$
  2. $\ce{NH4ClO3}$
  3. $\ce{Fe(CH3CO2)2}$
  4. $\ce{Fe(ClO3)2}$

Explanation:

Step1: Combine $\ce{NH4+}$ with $\ce{CH3CO2-}$

The charges balance as +1 and - 1, so formula is $\ce{NH4CH3CO2}$.

Step2: Combine $\ce{NH4+}$ with $\ce{ClO3-}$

The charges +1 and -1 balance, giving $\ce{NH4ClO3}$.

Step3: Combine $\ce{Fe^{2+}}$ with $\ce{CH3CO2-}$

Two $\ce{CH3CO2-}$ are needed to balance +2 charge of $\ce{Fe^{2+}}$, so $\ce{Fe(CH3CO2)2}$.

Step4: Combine $\ce{Fe^{2+}}$ with $\ce{ClO3-}$

Two $\ce{ClO3-}$ are required to balance +2 charge of $\ce{Fe^{2+}}$, resulting in $\ce{Fe(ClO3)2}$.
