Tang 06 valence bond theory and hybridization
The document discusses valence bond theory and hybridization. Valence bond theory explains how covalent bonds form through the overlapping of atomic orbitals. Hybridization occurs when atomic orbitals combine to form new hybrid orbitals. This allows atoms to form more bonds than their valence shell configuration suggests. Carbon can form 4 bonds through sp3 hybridization where one 2s and three 2p orbitals combine. Hybridization also explains bonding in molecules such as methane (CH4), ethene (C2H4), ethyne (C2H2), and benzene (C6H6). It further discusses how hybridization allows atoms like boron, beryllium, sulfur, and phosphorus to attain unusual bonding configurations
22 solution stoichiometry new
This document provides an overview of solution stoichiometry and includes 3 sample problems demonstrating how to use a balanced chemical equation to solve for unknown quantities.

Sample Problem 1 calculates molar concentration of sulfuric acid. Sample Problem 2 determines the minimum volume of sodium carbonate needed. Sample Problem 3 calculates the mass of silver chromate precipitate formed.
Tang 04 periodic trends
1) Atomic radius generally increases down a group and decreases across a period due to shielding effects of additional electron shells and increasing nuclear charge, respectively.
2) Ionization energy generally increases down a group and across a period as it becomes increasingly difficult to remove an electron due to greater nuclear attraction from less shielding and more protons. Exceptions occur when removing an electron would destabilize a full shell.
3) Electronegativity generally increases across a period as the effective nuclear charge felt by valence electrons increases with fewer shielding shells and more protons.

PAUL 10.10.doc
The document describes how to calculate the resistivity of copper using classical models. Given the mean free path and mean speed of electrons in copper at 300K, the resistivity is calculated to be 1.23x10-8 Ωm. Using the same model and equations but with temperature of 100K, the resistivity is calculated to be 6.5x10-8 Ωm. The classical model assumes temperature does not affect mean free path but does affect mean electron speed, following Maxwell-Boltzmann distribution, and this causes resistivity to increase with decreasing temperature.

Lecture2&3.pdf
Beaker A contained 0.74 g Ca(OH)2 in 100 ml water. This amount is less than the saturation point of 0.0814 g/100 ml. So the solution was unsaturated.
Beaker B contained 1.48 g Ca(OH)2 in 100 ml water. This amount exceeds the saturation point. So the solution was saturated.
The conductivity and pH would be higher in the saturated solution in Beaker B compared to the unsaturated solution in Beaker A. This is because in a saturated solution, more Ca2+ and OH- ions are available to carry current and increase pH respectively.
So the solution in Beaker B would be more conductive and have a higher pH value than

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
