Chapter 9, Problem 109AE
Some of the physical properties of H2O and D2O are as follows:
| Property | H2O | D2O |
| Density at 20°C (g/ml) | 0.997 | 1.108 |
| Boiling point (°C) | 100.00 | 101.41 |
| Melting point (°C) | 0.00 | 3.79 |
| ∆H°vap(kJ/mol) | 40.7 | 41.61 |
| ∆H°fus (kJ/mol) | 6.02 | 6.3 |
Account for the differences. (Note: D is a symbol often used for 2H, the deuterium isotope of hydrogen.)

Nitroglycerine ( C3H5N3O9) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by:
4C3H5N3O9(l)→6N2(g)+12CO(g)+10H2O(g)+7O2(g)
A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 203 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 40% dynamite explodes?
Acetylene can be made reacting calcium carbide with water.
CaC2 (s) + 2 H2O (l) →→ C2H2 (g) + Ca(OH)2 (aq)
Assume that you place 2.65 g CaC2 in excess water and collect the acetylene over water. The volume of the collected gas is 795 mL at 25.0 °C and a barometric pressure of 735.2 mm Hg. Calculate the percent yield of acetylene.
Note: the vapor pressure of water at 25.0 °C is 23.8 mm Hg.
Ethane (C2H6) is burned with atmospheric air, and the volumetric analysis of the dry products of combustion yields the following: 10% CO2, 1% CO, 3% O2, and 86% N2.
(a) What is the complete combustion equation?
(b) What is the theoretical oxygen?
(c) What is the percentage of excess air?

- 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.
