Yes, hydrogen diffuses faster than methane. The hydrogen molecule, H2, is the smallest of all molecules and it is considerably smaller than the methane molecule, CH4. Smaller molecules move faster, and therefore diffuse faster, at any given temperature, than larger molecules.
Covalent
Methane is one. Molecules that contain only carbon and hydrogen are called hydrocarbons.
d.polarWater molecules are polar covalent and therefore form attractions between the molecules called hydrogen bonds. Much of the heat that goes into raising the temperature of water to its boiling point goes to breaking the hydrogen bonds first.
The molecular shape of methane (CH4) is tetrahedral (Four hydrogen atoms surround a carbon atom in three-dimensional space) with sp3 orbital hybridization.

Well methane has a chemical structure of CH4 (one carbon surrounded by 4 hydrogen atoms), so for 2 methane you would need a total of 2 carbon atoms and 8 hydrogen atoms (or 4 H2 molecules)
Actually methane molecules have no oxygen atoms. Methane is an organic compound ( a gas at room temperature) which is composed of only carbon and hydrogen atoms. Each methane molecule has 1 carbon atom bonded to 4 hydrogen atoms by covalent bonds.
Covalent
Neptune's atmosphere is made up of hydrogen, helium, and methane.
The molecular formula for Methane is CH4 It's 1 atom carbon, 2 hydrogen molecules (Hydrogen molecules come in H2 gases) so the formula would be C + 2(H2) = CH4

Methane is one. Molecules that contain only carbon and hydrogen are called hydrocarbons.
Hydrogen bonding usually occurs between molecules that have a hydrogen atom bonded to either Fluorine, Oxygen or Nitrogen. So technically CH4 cannot hydrogen bond (certainly not between it's own molecules). However a recent A-Level exam paper had a multiple choice question which said that CH4 molecules CAN hydrogen bond with itself.
The molecule of methane has 5 atoms.
