Explanation:

Step1: Recall ion - charge rules

For ionic compounds, we use the charges of the constituent ions to write the formula. Sodium has a + 1 charge ($Na^+$) and nitrate has a - 1 charge ($NO_3^-$), so the formula for sodium nitrate is $NaNO_3$.

Step2: Determine calcium and carbonate ions

Calcium has a + 2 charge ($Ca^{2 + }$) and carbonate has a - 2 charge ($CO_3^{2 - }$). The formula for calcium carbonate is $CaCO_3$.

Step3: Identify magnesium and oxygen ions

Magnesium has a + 2 charge ($Mg^{2+}$) and oxygen has a - 2 charge ($O^{2 - }$). The formula for magnesium oxide is $MgO$.

Step4: Find ammonium and sulfide ions

Ammonium has a + 1 charge ($NH_4^+$) and sulfide has a - 2 charge ($S^{2 - }$). To balance the charges, the formula for ammonium sulfide is $(NH_4)_2S$.

Step5: Consider lead(II) and sulfate ions

Lead(II) has a + 2 charge ($Pb^{2+}$) and sulfate has a - 2 charge ($SO_4^{2 - }$). The formula for lead(II) sulfate is $PbSO_4$.

Step6: Analyze sodium and cyanide ions

Sodium has a + 1 charge ($Na^+$) and cyanide has a - 1 charge ($CN^-$). The formula for sodium cyanide is $NaCN$.

Step7: Look at potassium and hydroxide ions

Potassium has a + 1 charge ($K^+$) and hydroxide has a - 1 charge ($OH^-$). The formula for potassium hydroxide is $KOH$.

Step8: Determine silver and chloride ions

Silver has a + 1 charge ($Ag^+$) and chloride has a - 1 charge ($Cl^-$). The formula for silver chloride is $AgCl$.

Step9: Identify iron(III) and hydroxide ions

Iron(III) has a + 3 charge ($Fe^{3+}$) and hydroxide has a - 1 charge ($OH^-$). To balance the charges, the formula for iron(III) hydroxide is $Fe(OH)_3$.

Step10: Consider tin(IV) and perchlorate ions

Tin(IV) has a + 4 charge ($Sn^{4+}$) and perchlorate has a - 1 charge ($ClO_4^-$). To balance the charges, the formula for tin(IV) perchlorate is $Sn(ClO_4)_4$.

Step11: Analyze potassium and carbonate ions

Potassium has a + 1 charge ($K^+$) and carbonate has a - 2 charge ($CO_3^{2 - }$). To balance the charges, the formula for potassium carbonate is $K_2CO_3$.

Step12: Look at silver and nitrate ions

Silver has a + 1 charge ($Ag^+$) and nitrate has a - 1 charge ($NO_3^-$). The formula for silver nitrate is $AgNO_3$.
