A single water molecule can make three to four hydrogen bonds. A single water molecule can usually make three hydrogen bonds but in some cases it can make up to four.
Hint: If your high school Biology teacher is asking you this question the number of hydrogen bonds a molecule of water can make is almost always three (just remember one bond for each element).
C-C sigma bonds in acetone : 2 C-H bonds in water : 0 C-O bonds in water : 0 C-O sigma bonds in propanol : 1 C-C pi bonds in methanol : 0
Atoms that are highly electronegative, such as nitrogen, oxygen, and fluorine, when bonded to hydrogen, can form hydrogen bonds due to the large difference in electronegativity between the atoms. Examples of molecules that can form hydrogen bonds with hydrogen include water (H-O-H), ammonia (H-N-H), and hydrogen fluoride (H-F).
When hydrogen and oxygen combine to form water, a total of two bonds are formed. One bond is formed between each hydrogen atom and the oxygen atom. This results in the formation of H-O bonds.
ONE double bond (eg. in oxygen O2: O=O) or TWO single bonds (eg. in water H2O: H-O-H).
N-H bonds are typically considered hydrophilic due to the electronegativity difference between nitrogen and hydrogen, leading to partial charges on the atoms and the ability to form hydrogen bonds with water molecules.
Yes, H-bonds are weak bonds. The hydrogen bond is approximately 30 times weaker than a normal covalent bond.
2 covalent bonds: H-O-H. In other words, it makes water.

One molecule of water (H-O-H) contains two ionic bonds.
During the combustion of methane (CH4) to form water (H2O) and carbon dioxide (CO2), the bonds broken are the carbon-hydrogen (C-H) bonds in methane and the oxygen-oxygen (O=O) bonds in molecular oxygen (O2). These bonds are broken to form new bonds between carbon and oxygen in CO2, and hydrogen and oxygen in H2O.
2H2 + O2 + 2H2O 2H-H + O=O = 2H-O-H..not shaped like this !! The bonds in the reactants break and the bonds in the products form. The bonds in the H2 and O2 break and the bonds in the water form.

All four C-H bonds in methane are broken during combustion.
When hydrogen and oxygen combine to form water, a total of two bonds are formed. One bond is formed between each hydrogen atom and the oxygen atom. This results in the formation of H-O bonds.
ONE double bond (eg. in oxygen O2: O=O) or TWO single bonds (eg. in water H2O: H-O-H).
Two bonds in total. The oxygen atom forms two covalent bonds, one to each of two hydrogen atoms. This can be represented as H - O - H.
