Experiment 3 Objectives Separation by Solvent Extraction To separate a mixture consisting of a carboxylic acid and a neutral compound by using solvent extraction techniques. Introduction Frequently‚ organic chemists must separate an organic compound from a mixture of compounds‚ often derived from natural sources or products of synthetic reactions. One technique used to separate the mixture compounds is called extraction. Extraction is a process

INPUT AND OUTPUT DEVICES In computing‚ input/output‚ or I/O‚ refers to the communication between an information processing system (such as a computer)‚ and the outside world possibly a human‚ or another information processing system. Inputs are the signals or data received by the system‚ and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. I/O devices are used by a person (or other system) to

contributions to this growth are mobile devices. From your iPhones to your Galaxy tablets or iPads‚ these devices and many others affect us in a psychological context as well as technologically wise. According to Bos & Cuddy (2013) using our everyday mobile devices does not just affect our posture but also affects the way we behave or interact with our everyday duties . Nobel (2013) based on an experiment by Bos and Cuddy has also concluded that the way we use our devices will play a part in whether we became
