oxygen atoms are partially negatively charged
The phosphate groups in the DNA molecule give it a negative charge.
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.
Water is a polar molecule, meaning it has a positive and negative side. This allows it to interact with other polar and ionic substances, breaking them apart and forming bonds with the dissolved molecules. This process is known as hydration or solvation.
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
Ion-dipole attraction dictates that the negative pole of a water molecule will be attracted to the sodium cation and the positive pole of a water molecule will be attracted to the chloride anion.
there is no negative pole in h2o molecule

A water molecule is considered a polar molecule because of its shape. That is, its poles contain opposing charges, the positive and negative charge.
Because of the way the hydrogens bond to the oxygen in water, the molecular geometry is a bent or angular shape, and the oxygen has 2 lone pairs of electrons. This makes the oxygen part of the water molecule rather negative relative to the hydrogen part of the molecule, which is rather positive. Thus, there is a separation of charge, and this is what makes the water molecule so polar.
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
Water is a neutral molecule, meaning it does not have a positive or negative charge overall.
A polar molecule such as water
The positive calcium ions in calcium chloride are attracted to the negative oxygen atom in the water molecule, while the negative chloride ions are attracted to the positive hydrogen atoms in the water molecule.
A polar molecule is one that has a negative and positive end due to an uneven distribution of electron density. Water is a common example of a polar molecule, with its oxygen atom being partially negative and its hydrogen atoms being partially positive.
Water is polar and most chemicals are polar. The negative ends of the water molecule attract the positive ends of the chemical's molecules, and the positive ends of the water molecule attract the negative ends of the water molecule. This way the substance gets "pulled apart" from each other and mixes with water.
