The hydrogen atoms in a water molecule have slight positive charges. Particles with like charges (both positive or both negative) will repel each other.
A hydrogen bond forms between the hydrogen(s) of one water molecule, and the oxygen molecule of another water molecule.
In one water molecule, you have the slightly negatively charged oxygen side, and then you have the slightly positive hydrogen end. Because of this, the negative oxygen attracts positive hydrogens and vice versa in separate water molecules. This is where the hydrogen bonds are made.
A hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom(<-wikipedia). Hence, in a water molecule the positive hydrogen atoms are attracted to the negative oxygen atoms. Just know that the hydrogen bond mentioned above is not a chemical bond. If it were, it wouldn't be water anymore. Another force between water molecules are London Dispersion Forces.
Yes. Water is a polar molecule and forms hydrogen bonds with itself that helps to stick water molecules together. It can also form hydrogen bond with other polar organic molecules (with less nymber of carbon atoms) like alcohols, carboxylic acids etc., and is hence responsible for the solubility of these compounds in water.
covalent bond
A hydrogen bond forms between the hydrogen(s) of one water molecule, and the oxygen molecule of another water molecule.
They are polar and form hydrogen bonds
when a water molecule gains an hydrogen ion from another water molecule
A hydrogen bond between the oxygen of one water molecule and the hydrogen of another water molecule.
This attraction is called hydrogen bond, what causes higher boyling point in relation to compounds without such bonds

covalent bond
The hydrogen side of a water molecule has a slight positive charge.
H2O2 is the hydrogen peroxide.
Two water molecules can react to from hydrogen bonds. If one water molecule acts as an acid and donates a proton to another water molecule then hydronium ions an hydroxyl ions can be formed as well.
