    Detecting Substrings (C++ Version) Introduction A very common task that is often performed by programs that work with text files is the problem of locating a specific substring within the file. I am sure we’ve all done this many times when working with Word, Notepad, or other editors. Since we don’t have a GUI or other means of displaying the contents of a file all at once, let’s modify the problem slightly. Rather than locating a specific substring within a...

    Free the ‘trapped’ fan, capture more venue sales Published June 6, 2005: Page 22 SBJ by Bill Sutton In an age when consumers have multiple choices, why does a sporting venue espouse the philosophy that those consumers are “trapped” in the venue for three to four hours and, therefore, at the mercy of the organization, which tends to restrict their options and choices within the venue? Why not view each consumer as an asset to be developed and cultivated for...

    Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...

    Conductivity of Solutions For Che 2A at RCC Introduction Electrolytes are compounds which conduct electricity when dissolved in water. Strong electrolytes consist of ionic compounds which dissociate completely when dissolved in water, AND molecular compounds which completely ionize when dissolved in water. The reactions below illustrate the dissociation reaction of strong electrolytes: Na (aq) + Cl(aq) но NaCl(s) H30 CaBra(s) HO HCl(e) Ca(aq) + 2Br (aa) H*(aq) + C'(aq) Conductivity is a measure of the ability of water to pass...

    Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...

    Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
