Explanation:

Question 1

Lead (II) has a charge of +2. Nitrate ion (\(NO_3^-\)) has a charge of -1. To balance the charges, we need 2 nitrate ions for each lead ion.

Potassium has a charge of +1 and iodide has a charge of -1. To balance the charges, we need one potassium ion and one iodide ion.

Answer:

Pb\((NO_3)_2\)
