Nanotechnology, or technology utilizing 1100 nm sized particles, has rapidly expanded in the past few decades, with potential applications ranging across far-reaching fields such as electronics, medicine, biomaterials, and consumer products, to name a few. One of the primary advantages of nanoparticles is the presence of large surface/mass ratios, resulting in enhanced surface activities compared to bulk materials. a Use the density of silver (10.49 g/cm3) to determine the number of Ag atoms in a spherical 20.-nm silver particle. b In the crystalline metallic environment, the measured radii of silver atoms has been measured to be 144 pm. Use this to calculate the atomic packing fraction of a 20.-nm silver particle. In other words, calculate the ratio of the volume taken up by Ag atoms to the volume of the entire nanoparticle. c Based on the result of part (b), silver conforms to which type of cubic crystal lattice?

Compound Chemical formula Hvap (kJ⋅mol−1) Boiling point (K) Hfus(kJ⋅mol−1) chloromethane CH3Cl 21.40 249.06 6.43 water H2O 40.65 373.15 6.01 hydrogen sulfide H2S 18.67 213.60 18.67 1. Trouton's rule states that the molar enthalpy of vaporization of a liquid that does not have strong molecular interactions such as hydrogen bonding or ion‑ion attractions is given by Hvap=(85 J⋅K-1⋅ mol-1)Tb Where Tb is the normal boiling point of the liquid in kelvins. Apply Trouton's rule to estimate the value of Hvap for these compounds: chloromethane: Hvap= ? kJ/mol water: Hvap= ? kJ/mol hydrogen sulfide: Hvap = ? kJ/mol
From the following information, sketch and label the phase diagram for CH3COOH. The melting point of the solid is 16.6°C under its own vapour pressure of 9.1 mm Hg. Solid CH3COOH exists in two modifications, I and II, both of which are denser than the liquid, and I is the stable modification at low pressure. Phases I, II, and the liquid are in equilibrium at 55.2°C under a pressure of 2000 atm. The transition temperature from I to II decreases as the pressure is decreased.
