Answer: option 4. polar, with the chlorine end having a partial negative charge.
Explanation:
1) A polar bond is a covalent bond in which the electrons are pulled more strongly by one of the atoms and then they are not evely distributed between the two linked atoms.
2) That happens when the two atoms have diferent electronegativities.
3) As the per periodic table trend of the electronegativity, you can predict that the electronetativity of Cl is higher than that of P.
In fact, in a table of electronegativities you can find that the electronegativity of Cl is 3.16 while the electronegativity of P is 2.19.
This is a 3.16 - 2.19 = 0.97 difference.
As explained, that difference means that Cl will pull the electrons more strongly resulting if a partial negative charge on Cl and a partial positive charge on P, i.e. a polar bond.

At some convergent boundaries.
Answer:
65.4 is the mass for 1.9×10²⁴ atomsof Pb
Explanation:
1mol of atoms of Pb has → NA (6.02×10²³ atoms) and weighs → 207.2 g
Therefore 1.9×10²⁴ atomsof Pb may weigh (1.9×10²⁴ . 207.2) / NA = 65.4 g
