Answer is: <span>lumps os sugar dissolving in water.
Sugar has very good solubility in water and it dissolves readily, which is </span><span>example of a physical change.
</span>Gibbs free energy (G) determines if reaction will proceed
spontaneously, if ΔG is negative, reaction is spontaneous <span>(ΔG = ΔH - T·ΔS).
</span>In other examples, reactions are spontaneous in reverse way, for example spontaneous is forming sodium chlorine from sodium metal and chlorine gas, but not sodium chloride forming sodium metal and chlorine gas, because a lot of energy is needed for that reaction.
C. The Seasons change during the year.
Would be the correct answer.

Answer:
Stretch band
Explanation:
Bc mechanical energy is the energy of movement so it’s all around us and so anything that moves us basically mechanical energy therefore a stretch band has mechanical energy
The Lewis structure of the hydrogen cyanide molecule is represented by the image shown.
<h3>
What is the Lewis structure?</h3>
We know that the Lewis structure is showing us the relationship between the electrons pairs in the compound and its overall properties. The Lewis structure consists of the symbol of the element and the electrons pairs that surround the atom.
We can see that in hydrogen cyanide there is a nitrogen atom and there is a hydrogn atom and also one carbon atom. The bond between carbon and nitrogen is covalent while the bond between hydrogen and the cyanide moiety is covalent.
