O-O single bonds and H-O single bonds in molecules.
H-O single bonds in molecules.
O=O double bonds in molecules.
<h3>Explanation</h3>
How many valence electrons do atoms in each molecule need for them to be stable?
Each H atom needs two valence electrons to be stable.
Each atom of an element other than H needs eight valence electron to be stable.
There are two H atoms and two O atoms in an molecule. Atoms in each need more electrons to be stable.
There are two H atoms and one O atom in an molecule. Atoms in each molecule need more electrons to be stable.
There are two O atoms in an molecule. Atoms in each molecule need more electrons to be stable.
How many chemical bonds in each molecule?
Each chemical bond adds one valence electron to each bonding atom. Each chemical bond connects two atoms. As a result, each chemical bond adds two valence electrons to the molecule.
Each molecule needs chemical bonds.
Each molecule needs chemical bonds.
Each molecule needs chemical bonds.
What chemical bonds are these? Again, each H atom needs only one more valence electron to be stable. It will share only one electron with O and form one H-O bond. The rest of the chemical bonds are between O atoms.
There are two H atoms in each molecule, which form two H-O bonds. Two of the three chemical bonds in this molecule are H-O. The other is an O-O single bond between the two O atoms.
There are two H atoms in each molecule, which form two H-O bonds. Both chemical bonds in this molecule are H-O. There's no O-O bond in this molecule.
There is no H atom in molecules. Both chemical bonds are between O atoms. However, there are only two O atoms. There must be two chemical bonds between the two O atoms. That bond will be an O-O double bond.
Photosynthesis takes place in the chloroplasts, that is why the chloroplasts is green. The function of this organelles is to create energy into sugar from the sunlight.
