What causes hydrogen bonding between water molecules? covalent bonds between water molecules, difference in electronegativity between the oxygen atom and hydrogen atoms, oxygen atoms contain more electrons than hydrogen atoms, ionic bonding

The answer should be the difference in electro negativity because all atoms want to become equal in respect with their charges and an oxygen has a -2 charge and a hydrogen is +1 so 2 hydrogen bonding with 1 oxygen makes and equal charge.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you

The answer should be geothermal i hope i’m right message me if i’m wrong and i’ll change my answer and fix it for you
