Density is mass/volume so if you double the mass you would also double the volume which means density would stay the same. Density is the amount of of matter in a given area and it is constant for the substance regardless of differences in mass or volume.
Answer:
The product of the pressure and volume.
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).
