QUESTION 8 What is the best explanation for why solid sodium chloride CANNOT conduct electricity and why molten sodium chloride can? There are ions present in NaCI (s), but not in NaCl (1)- There are ions present in NaCl (1) but not in NaCl (s)- The ions in NaCl (5) are NOT mobile, but they are mobile in NaCl (1). The ions in NaCl (s) are mobile, but they are NOT mobile in NaCl (1)- QUESTION 9 Consider the experiment "Molar Mass of a Copper Compound". If 2.5 g of the compound CuX reacts with zinc to produce 0.0133 moles of copper metal, what is the molar mass of the copper compound? Save Click Save and Submit to save and submit.

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
