a typical aspirin tablet contains 324 mg of aspirin (acetylsalicylic acid, C9H8O4, Ka = 3.0×10-4). Imagine you dissolve two aspirin tablets in a 275 mL glass of water. Calculate the solution's pH.
Chemical-plant equipment costs rarely vary in proportion to size. In the simplest case, cost C varies with size S according to the allometric equation 18 Chemical Engineering Thermodynamics C = ?S?
The stereochemistry of the more highly substituted alkenes is difficult to define using the cis and trans designations. Therefore, a more systematic manner of indicating stereochemistry in these systems has been developed that uses an E and Z nome..
