Unit 8 Textbook Notes 12.1 The N2O4-NO2 Equilibrium System When you put a sample of N2O4‚ a colorless gas‚ in a closed container at 100C a reddish-brown color starts to show. This is due to NO2 formed by the decomp. of part of the original substance. The forward and reverse reactions are taking place at the same rate. The concentrations of species present remain constant with time. These concentrations are independent of the direction from which equilibrium is approached. The equilibrium constant

Principles of Sigma-Delta ADCs Abstract: This article covers the theory behind a Delta-Sigma analog-to-digital converter (ADC). It specifically focuses on key digital concepts of oversampling‚ noise shaping‚ and decimation filtering. Introduction Sigma-delta converters offer high resolution‚ high integration‚ and low cost‚ making them a good ADC choice for applications such as process control and monitoring. The analog side of a sigma-delta converter (a 1-bit ADC) is very simple. The digital side

The Working Memory Model (WMM) is a theory by Baddeley and Hitch in 1974. The theory replaces the idea that there is a single Short Term Memory (STM) from Atkinson and Shiffrin (1968)‚ it suggests that the STM is a flexible multi-component system. The WMM suggests that the STM is controlled by the Central Executive (CE) which controls attention‚ planning and synthesising information. The Central Executive is a flexible system which means it can process audio‚ visual and sound information‚ it also

Although the actual occurrence for the KFS syndrome is unknown‚ it is estimated to occur 1 in 42‚000 newborns worldwide. In addition‚ females seem to be affected slightly more often than males Treatment for Klippel–Feil syndrome is symptomatic and may include surgery to relieve cervical or

Introduction There are two urgent issues for us to figure out when dealing with two questions: firstly‚ whether Ron’s exclusion clause on the receipt or the sign is effective based on the fact that Winston does not know that existence of exclusion clause. Secondly‚ whether Winston accepts Ron’s exclusion clause at the right time and whether it can exclude Ron for liability. (a) Whether Winston is bound by the words on the receipt or the sign? As we can see in the case introduction‚ Ron

CHEM 3411‚ Fall 2010 Solution Set 5 In this solution set‚ an underline is used to show the last significant digit of numbers. For instance in x = 2.51693 the 2‚5‚1‚ and 6 are all significant. Digits to the right of the underlined digit‚ the 9 & 3 in the example‚ are not significant and would be rounded off at the end of calculations. Carrying these extra digits for intermediate values in calculations reduces rounding errors and ensures we get the same answer regardless of the order of arithmetic
