Answer:

Explanation:
Let's rewrite the given word equation in its chemical balanced equation representation:
1. Lead(II) nitride is represented by lead, Pb, in an oxidation state of 2+, while nitride is a typical nitrogen anion with a state 3-. As a result, the lowest common multiple between 2 and 3 is 6, meaning 2 lead cations are needed to balance 3 nitrogen anions:
.
2. Ammonium sulfate consists of an ammonium cation with a 1+ charge and sulfate anion with a 2- charge, two ammonium cations needed:
.
3. Lead(II) sulfate would have one lead cation and one sulfate anion, as they have the same magnitude of charges with opposite signs:
.
4. Ammonium nitride would require three amonium cations to balance the nitride anion:
.
Let's write the balanced equation:

Answer:
7 to 1
Explanation:
As you move from row ----- to row ------ in the periodic table, the atomic radius of the elements DECREASES.?
And we have 7 rows in a periodic table, so the answer has to either 1 to 7 or 7 to 1
Theoretically,
Atomic size increase as we move from top to bottom as an extra shell gets added up with every period.
SO, the answer is, 7 to 1
