Final answer:
The concept that fresh zinc oxide causes chills is not supported by scientific literature, and it likely stems from a misunderstanding. Zinc oxide has various applications, including in sunscreens and medicinal ointments, and its lattice energy is typically higher than that of NaCl.
Step-by-step explanation:
The question 'Why does fresh zinc oxide cause chills but old oxide does not' seems to be a misinterpretation as there is no documentation or chemical reason why fresh zinc oxide would cause physiological 'chills'. Zinc oxide, or ZnO, is used in a variety of products such as sunscreen, rubber goods, and medicinal ointments. The reference to 'fresh' vs. 'old' zinc oxide may pertain to the amount of exposure to pollutants which can discolor the compound, though this discoloration would not be associated with a sensation of chills.
As for the lattice energy of ZnO compared to that of NaCl, ZnO would typically have a higher lattice energy due to the higher charges on zinc and oxide ions compared to the sodium and chloride ions in NaCl, leading to a stronger electrostatic attraction between ions in the ZnO lattice.
