When water evaporates do the covalent bonds between O atoms and H atoms break or do the hydrogen bonds break and why?
When water evaporates, it is the hydrogen bonds between water molecules that break, not the covalent bonds within each water molecule. The hydrogen bonds are weaker intermolecular forces that hold water molecules together. Breaking these bonds allows the water molecules to escape as vapor.
What is the difference between water molecules and the bond within the water molecule?
Water molecules are composed of one oxygen atom and two hydrogen atoms. The bonds within a water molecule are covalent bonds, which are strong bonds that hold the atoms together. These covalent bonds involve the sharing of electrons between the oxygen and hydrogen atoms within the water molecule.
Does water have both ionic and covalent bonds?
Water molecules have covalent bonds between the oxygen and hydrogen atoms within the molecule. However, water molecules can also form hydrogen bonds with each other due to the difference in electronegativity between oxygen and hydrogen atoms. These hydrogen bonds are not considered ionic bonds.
Will the attraction between various combinations of atoms produce bonds which form molecules?
Yes, the attraction between atoms can lead to the formation of chemical bonds, which can then combine to form molecules. These bonds may form through the sharing or transfer of electrons between atoms, resulting in stable configurations of atoms in a molecule.
When water freezes to form ice what connects the water molecules?
hydrogen bonds
What determines the cohesiveness of water molecules?
The cohesiveness of water molecules is determined by hydrogen bonds. These bonds form between the hydrogen atoms of one water molecule and the oxygen atoms of neighboring water molecules, creating a strong attraction that allows water molecules to stick together.

Are attractions between water molecules called polar bonds?
No, the attractions between water molecules are not called polar bonds; they are referred to as hydrogen bonds. Polar bonds occur within the water molecule itself, where the oxygen atom is more electronegative than the hydrogen atoms, creating a dipole moment. The hydrogen bonds form between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atoms of neighboring water molecules, contributing to water's unique properties.
Where do hydrogen bonds occur in biological molecules?
Hydrogen bonds occur between hydrogen atoms and electronegative atoms like oxygen or nitrogen in biological molecules such as DNA, proteins, and water.
Are Water molecules are held together by ionic bonds?
No, water molecules are held together by covalent bonds, where electrons are shared between the atoms. Ionic bonds involve the transfer of electrons between atoms of different elements. Water is a polar molecule due to the unequal sharing of electrons, resulting in a slightly negative oxygen atom and slightly positive hydrogen atoms.
What is water-water bonds called in a beaker of water?
In a beaker of water, the bonds between water molecules are called hydrogen bonds. These bonds are formed between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atom of another water molecule.
Which type of chemical bonds form between water mlecules?
The most important intermolecular bond between water molecules is the hydrogen bond. Hydrogen bonds are formed between the partially positive hydrogen atoms of one molecule, and the partially negative oxygen atoms other molecules.
What bond are disrupted in the presence of water?
Hydrogen bonds are commonly disrupted in the presence of water. These bonds are weak forces of attraction between hydrogen atoms and oxygen, nitrogen, or fluorine atoms in molecules. When water molecules interact, the polar nature of water allows it to break and form hydrogen bonds with other molecules.
