What are polyethene molecules made of?
Polyethylene is a polymer of ethylene and it has carbon and hydrogen atoms.
Does ethylene glycol molecules have a greater attraction for cyclopentane than for each other?
No, ethylene glycol molecules have a much stronger attraction for each other due to hydrogen bonding, compared to their attraction for non-polar molecules like cyclopentane. This is due to the polar nature of the ethylene glycol molecule, which forms strong intermolecular forces with other ethylene glycol molecules.
What are the main ingredients of ethylene?
Ethylene contain hydrogen and carbon.
Which two atoms in this formaldehyde molecule?
There are three elements present in formaldehyde. Namely, they are carbon, hydrogen and oxygen.
What happens during the hydrogenation of ethylene?
During hydrogenation of ethylene, ethylene molecules react with hydrogen gas in the presence of a catalyst (typically metal catalysts like palladium or nickel). The double bond in ethylene breaks, and hydrogen atoms add to the carbon atoms, forming ethane. This process converts unsaturated hydrocarbons (like ethylene) into saturated hydrocarbons (like ethane).
How many hydrogen atoms are in six molecules of ethylene glycol HOCH2CH2OH?
The chemical formula for ethylene glycol is C2H6O2, so in 6 molecules there would be 36 atoms of hydrogen
How many hydrogen atoms are in six molecules of ethylene glycol C2H6O2?
There are a total of 24 hydrogen atoms in six molecules of ethylene glycol (C2H6O2), as each molecule contains 4 hydrogen atoms.

Polyethylene is a polymer of ethylene and it has carbon and hydrogen atoms.
What are polyethylene molecules made of?
Polyethylene is a polymer of ethylene and it has carbon and hydrogen atoms.
Is formaldehyde a hydrogen bond?
No, formaldehyde is not a hydrogen bond. Formaldehyde is a chemical compound with the formula CH2O consisting of a carbon atom bonded to an oxygen atom and two hydrogen atoms. Hydrogen bonds are specific types of interactions between a hydrogen atom and a highly electronegative atom like oxygen or nitrogen.
Does ethylene glycol molecules have a greater attraction for cyclopentane than for each other?
No, ethylene glycol molecules have a much stronger attraction for each other due to hydrogen bonding, compared to their attraction for non-polar molecules like cyclopentane. This is due to the polar nature of the ethylene glycol molecule, which forms strong intermolecular forces with other ethylene glycol molecules.
What are the main ingredients of ethylene?
Ethylene contain hydrogen and carbon.
What intermolecular forces are present in formaldehyde?
Formaldehyde contains dipole-dipole interactions as a polar molecule with an electronegative oxygen atom. It also has London dispersion forces due to temporary dipoles that can form. Hydrogen bonding can occur between the hydrogen atom and oxygen atom in neighboring molecules.
Can you sketch the hydrogen bonding between ethylene glycol molecules?
In ethylene glycol, hydrogen bonding occurs between the hydrogen atoms of one molecule and the oxygen atoms of another molecule. This leads to the formation of a network of hydrogen bonds between adjacent molecules, resulting in a higher boiling point and viscosity compared to molecules without hydrogen bonding.
What elements are in formaldehyde?
Formaldehyde is composed of carbon, hydrogen, and oxygen atoms. Its chemical formula is CH2O.
What type of gas is expected to effuse faster from a container?
This gas is hydrogen, a gas with small molecules.
Which two atoms in this formaldehyde molecule?
There are three elements present in formaldehyde. Namely, they are carbon, hydrogen and oxygen.
