If they have 3 chemistry classes with 24 students, than there are 72 students in total. Each student requires 4 test tubes. 72 * 4 = 288 test tubes. Our answer is C.) 288 test tubes
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:
neutralization reaction
Explanation:
The reaction of an acid with a base is called a neutralization reaction. The products of this reaction are a salt and water.
