Answer:-
The hydrogen atoms have partial positive charges
Explanation:-
In a water molecule there are twp atoms hydrogen and oxygen.
Oxygen has more electronegativity than hydrogen. So the electrons in the bond between Oxygen and hydrogen are more towards oxygen. So hydrogen has a partial positive charge.
The Cl- has negative charge. Positive charge is attracted by negative charge.
Due to this hydrogen atoms in a water molecule are attracted to Cl- ions in sodium chloride (NaCl).

Three things that should happen for a chemical reaction to occure :
1. Position of electrons must change
2. Chemical bonds must be formed and broken between atoms and
3. No changes should happen to the nuclei
