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:
d. pair
Explanation:
because,H3PO4 is a strong acid
Answer:
The thermal energy of an object is the total energy of the particles in a material. A 5-kg chunk of aluminum and a 5-kg block of silver that are at the same temperature have the same thermal energy. Heat flows from a higher temperature to a lower temperature.
If Ba and I are to bond ionically, the nonmetal will gain electrons, giving it a negative charge, and the metal will lose electrons, giving it a positive charge. So Ba is a metal and I is a nonmetal. Iodine would accept electrons from the other atom.
