What is the dominant form of chemical bonding exhibited by minerals such as native gold?
Covalent bonds Covalent bond is the strongest of the chemical bonds. Minerals with covalent bonds are usually insoluble, very stable, have very high melting points, and non conductive. Minerals with ionic bonds usually have moderate hardness, high melting point, poor conductors, due to the stability of ions.
Which molecule has the highest melting point?
Hydrogen-bonding molecules
Is the melting of table salt physical or chemical?
The melting point is a physical property of materials.
Is the melting of an ice cube considered a physical change or chemical change Explain your reasoning?
The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.

Explain why burning butter is a chemical change but melting is not?
Melting: change of phase, a physical phenomenon without change of the composition. Burning: a reaction of oxydation, a change of composition - a chemical change.
Explain whyIn Group 17 HF has abnormally high melting and boiling points as compared to other hydrides of the group?
Hydrogen bonding.
Why are plastics so versatile?
by melting plastic

Why plastics should not be manufactured?
Green house gases created by melting and making it(melting plastic). The waste produced after use. (rubbish)
Which molecular solid would have the highest melting?
one with hydrogen bonding.

Is melting a type of Chemical change?
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
Is melting a chemical property?
No. Melting is a physical change.
