Question

1. what kind of bond holds the hydrogen to the oxygen in one water molecule? 4. what kind of bonds can hold two separate water molecules together?

Explanation:

Question 3

In a water molecule ($H_2O$), the bond between hydrogen and oxygen within the same molecule is a covalent bond. Covalent bonds form when atoms share electrons. Oxygen and hydrogen share electrons to achieve stable electron configurations.

Two separate water molecules are held together by hydrogen bonds. A hydrogen bond is an intermolecular force that occurs when a hydrogen atom bonded to a highly electronegative atom (like oxygen in water) is attracted to another electronegative atom (oxygen of another water molecule).

Answer:

Covalent bond
