Yes, sigma and pi bonds can be found in the same molecule. Sigma bonds are formed by head-on overlapping of atomic orbitals, while pi bonds are formed by sideways overlap of p-orbitals. Double and triple bonds, for example, contain both sigma and pi bonds.
A common type of covalent bond found in diatomic molecules is a sigma bond. In a sigma bond, the electron density is concentrated along the axis between the two atoms, resulting in the sharing of electrons in a head-to-head overlap of atomic orbitals. This type of bond is particularly strong and is responsible for holding the two atoms together in a diatomic molecule.
This is hard to answer as there is no specific answer on this in any literature i stumbled across. I'd say it has 3 bonds. I sigma and IIpi bonding orbitals. The energy diagrams say so. I have the same dilema as i promised my organic chemstry prof. i'd do a detailed model of a O2 molecule.My answer? ... 3 bonding orbits.
Both ethane and ethene have the same number of carbon atoms per molecule, which is two. However, the difference lies in the type of bonds between the carbon atoms - ethane has single bonds, while ethene has a double bond.
In ethylene (C2H4), the carbon atoms are sp2 hybridized which allows for planar geometry due to the formation of three sigma bonds in a trigonal planar arrangement. This planar structure minimizes electron repulsion and stabilizes the molecule.
Carbon and hydrogen do not typically form hydrogen bonds with each other in a molecule. Hydrogen bonds form between a hydrogen atom bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) and another electronegative atom in a different molecule.
Sigma bonds are those lie on the axis between two atoms. Pi bonds are non axial with electron density above and below. For example in methane the bonds are all single bonds and single bonds are always sigma bonds as the electron density maximum is between the two bonded atoms. this bond can be thought of being formed by the overlap of an sp3 hybrids orbital on the carbon and an s orbital on the hydrogen. In ethene (ethylene), a molecule where all of the atoms lie in the same plane, there is sigma bond (sp2 hybrid on each carbon overlapping) and a pi bond with electron density above and below the sigma bond which is formed by the overlap of p orbitals that are at right angles to the plane of the molecule. See wikipedia "ethylene" for pretty pictures.

ionic bonds
Both have, carbon and hydrogen and carbon-carbon sigma bonds.
No, methane (CH4) does not have any resonance structures because it does not have any delocalized electrons to allow for resonance delocalization.
The mRNA molecule is completed by the formation of phosphodiester bonds between the RNA nucleotides during the process of transcription. This results in a single-stranded molecule that carries the genetic information from DNA to the ribosome for protein synthesis.
Isovalent hyperconjugation structures are resonance structures in which a sigma bond adjacent to a pi bond donates electron density to the pi system. This results in stabilization of the molecule due to delocalization of electrons. Isovalent hyperconjugation is commonly observed in organic compounds with multiple bonds.

No, hydrogen is a diatomic atom, which means it bonds with itself naturally, and since argon it is a noble gas, it is found alone in nature. This means that 1 molecule of hydrogen has two atoms, while 1 molecule of Argon has 1 atom.
