Understand the key terms in the question: a 'compound' is a substance formed when elements combine in fixed proportions.
Recall that a 'chemical bond' is the force that holds atoms together in a compound, involving the sharing or transfer of electrons.
Recognize that a 'physical mixture' involves no chemical bonding; substances are simply mixed without forming new compounds.
Note that a 'nuclear reaction' involves changes in the nucleus of atoms, not the formation of chemical compounds.
Understand that a 'phase change' refers to changes in the state of matter (solid, liquid, gas) without forming new compounds.
