Answer:
ΔH > O and ΔH > TΔS
Explanation:
When a reaction is non-spontaneous even though the standard entropy change of the reaction is large and positive the reason is the reaction is highly endothermic and dominates the term TΔS in the standard Gibbs free energy expression:
ΔG = ΔH-TΔS
Remember that for an endothermic reaction to be spontaneous ΔG < 0 and this can occur only if the term TΔS is greater than ΔH. This is not the case for quartz which requires a good quantity of energy to overcome its crystaline 3D lattice in which the oxygen are shared between 2 silicon atoms.
Answer:
It won't be good.
Explanation:
In the core of the sun, hydrogen is produced by nuclear fusion. when the sun ages, it starts to run out of the hydrogen. when it runs out, nuclear fusion can't generate heat, and then the sun expands, becoming a red giant.
1.) Find The Number of Half Lives Passed:
