D. Itd be 4+. Hope it helps
<span>The molecular formula for Copper(II) Sulfate is CuSO4. 1 mole is equal to 1 moles Copper(II) Sulfate, or 159.6086 grams.I hope this is right </span>
The polar characteristic of water helps it form strong bonds with other water molecules.
<h3>What is polar structure?</h3>
A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative.
The attractive force between water molecules is a dipole interaction.
The hydrogen atoms are bound to the highly electronegative oxygen atom (which also possesses two lone pair sets of electrons, making for a very polar bond).
Hence, option D is correct.
