<span>If the the level of water in a container is compared before and after the fusion, it can be realized that the ice has a higher level than that of liquid water: solid and liquid water does not have the same volume.
</span><span>We can generalize:
A state change always causes a change in volume.
Comment:
Water is an exception, volume increases during a melting for most of substances.</span>
Answer:
True
Explanation:
Resonance is a concept in chemistry that describes bonding in polyatomic molecules or ions whose structure cannot be efficiently described by a single Lewis structure. Individual resonance structures do not actually exist, that is, they are not real. None of the contributing resonance structures can be said to adequately represent the molecule or ion. However, the hybrid of all the possible resonance structures of the molecule or ion gives a holistic representation of the exact structure of the molecule or ion.
