Explanation:,Hydrogen bonding is a special type of dipole-dipole attraction between molecules ,not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
Answer:
Noble Gases
Explanation:

This is a build up of lava which came out of the volcano in previous eruptions, once this lava came out of the volcano it cooled and hardened, over many eruptions layers of hardened volcanic rock will form. The layers are slanted as gravity acts on the lava so it flows down and a little further from the cone.
Answer: Clay
Explanation:
Putty is a cementing material which is used for white wash and filling up the holes on the wall. It is a mixture of calcium carbonate along with oil solvent. The dough is a powdery substance. When putty and dough are combined they form a clay which is of high density as compared to other two materials. It is thick and rigid.
So, when a putty and dough combines then a clay will form.
