Explanation:

Step1: Identify ions in magnesium bicarbonate

Magnesium has a +2 charge ($Mg^{2 +}$) and bicarbonate ion is $HCO_3^{-}$.

Step2: Balance charges

To balance the +2 charge of magnesium, we need 2 bicarbonate ions. So the formula is $Mg(HCO_3)_2$.

Step3: Identify ions in potassium nitrite

Potassium has a +1 charge ($K^{+}$) and nitrite ion is $NO_2^{-}$.

Step4: Write formula

Since the charges +1 and - 1 balance each other, the formula is $KNO_2$.

Answer:

Part C: $Mg(HCO_3)_2$
Part D: $KNO_2$
