How do the melting and boiling points of water compare to that of other molecular compounds of similar molar mass? Select one:
a. They are both much lower.
b. They are both about the same.
c. The melting point is much lower, while the boiling point is much higher.
d. They are both much higher.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
