I don’t understand this one sorry
Answer:
Work = Path function.
Energy = State function.
Distance traveled = Path function.
Enthalpy = State function.
Heat = Path function.
Explanation:
Hello,
At first, a state function is a property whose value does not depend on the path taken to reach that specific function or value, as in this case, energy and enthalpy.
On the other hand, path functions are functions that depend on the path taken to reach that specific value, as in this case, work, distance traveled and heat since different paths will provide different values for each one of them.
Best regards.

Answer:
Option b) polyatomic ions
Explanation:
Polyatomic ions are ions consisting of two or more atoms.
From the question given above, we can see that each ions consist of more than one atom as shown below:
Ions >>>>>> Number of atom present
NH4+ >>>>> 2
CO32− >>>> 2
PO43− >>>> 2
Thus, we can say that the above ions are polyatomic ions.
