Hazardous materials are grouped into classes identifying their similarities in composition and structure.
<h3>Why hazardous materials are grouped into classes?</h3>
The hazardous materials are grouped into classes in order to tell us about the severity of hazard and it is done on the basis of similarity in composition.
So we can conclude that hazardous materials are grouped into classes identifying their similarities in composition and structure.

Answer:
2As2S3 + 9O2 = 2As2O3 + 6SO2
Explanation:
Hydrogen bonds are stronger than the dipole dipole attraction force present in any molecule.
<h3>What is bonding in molecules?</h3>
Bonding is a type of attraction force which is present between the different atoms or elements of any substance.
- Dipole dipole attraction force is a weak force as compared to the hydrogen bonding and present between any two oppositely charged atoms.
- Hydrogen bond is present between the hydrogen atom and more electronegative atoms like O, S, N and F.
Hence main difference is that hydrogen bond is only present between the hydrogen atom and more electronegative.
