eBooks de Química, página 2 de 19

Este libro es una compilación de experiencias y problemas resueltos durante muchos años de la asignatura de Ingeniería de Reactores de la carrera universitaria de Ingeniería Química a nivel licenciatura en la Universidad Autonoma del Estado de Morelos. El objetivo es que sea una guia practica a los estudiantes para la resolucion de problemas, por lo que contiene unicamente una breve explicacion y desarrollo conceptos teoricos elementales necesarios para entender la manera en que los problemas fueron resueltos. En ningun momento pretende sustituir las grandes obras de los autores Octave Levenspiel, Scott Fogler, J. M. Smith, entre otros, y se invita a los interesados a consultarlas para un aprendizaje mas profundo y mayor entendimiento de los topicos tratados, ya que este libro esta basado en muchos de los conceptos contenidos en ellas. Finalmente, se menciona que en muchos de los problemas se muestra como usar herramientas computacionales para simplificar la resolucion, sobre todo en aquellos casos donde se usan metodos numericos con procedimientos iterativos, o bien la resolucion de ecuaciones diferenciales y sistemas de ecuaciones no lineales complejas. Dichas herramientas computacionales son hojas de calculo en Microsoft Excel, que es un programa de facil acceso, y PolymathPlus que al momento de la redaccion de este libro tiene una version libre de facil uso en internet.

In "The Wonders of Radium," Maynard Shipley offers a penetrating exploration of radiums transformative impact on science, medicine, and society during the early 20th century. Through meticulous research and articulate prose, Shipley delves into the marvels of radium, weaving through its discovery, the scientific advancements it inspired, and the ethical dilemmas it posed. His literary style resonates with a blend of scientific accuracy and accessibility, inviting both scholars and lay readers into the intricate dance of discovery and innovation that marked the radium era, while situating the narrative within the broader context of the burgeoning field of radioactivity and its implications for humanity. Maynard Shipley, a prominent chemist and writer, was at the forefront of the early scientific discourse on radioactivity. His background in chemistry and his experiences during the vibrant scientific milieu of the early 1900s significantly influenced his perspective on radiums potential. Shipleys engagement with the scientific community and deep understanding of the complexities surrounding radium fueled his commitment to elucidating both its wonders and its risks, crafting a narrative that serves as both a celebration of scientific achievement and a cautionary tale. Readers seeking a profound understanding of both the capriciousness of scientific discovery and the ethical considerations accompanying technical advancements will find "The Wonders of Radium" to be an essential addition to their library. Shipleys insightful commentary and historical context create a compelling case for reconsidering our relationship with science, making this book a must-read for those interested in the interplay between discovery and morality in the history of science.

Este libro tiene como objetivo principal el estudio del equilibrio químico de las disoluciones acuosas en sistemas homogéneos y heterogéneos. Como un apoyo para las asignaturas de Química Analítica, la informacion que se expone esta dirigida a los alumnos de las carreras de Quimica o areas afines.

Los elementos químicos de la tabla periódica son los átomos con los que está hecho el Universo. No falta ni sobra ninguno. Cada átomo se distingue del otro dependiendo de cuántos electrones, protones o neutrones tenga en su interior, habitando la naturaleza en forma armoniosa, como por arte de magia. Cuentos y leyendas se han escrito desde que tal magia empezo a descifrarse. En los textos que componen este libro, sus diversos autores nos comparten el origen, la historia y las caracteristicas mas importantes de cada uno de los elementos quimicos que han sido descubiertos, lo cual nos lleva, tambien, a repasar algunas de las paginas mas importantes de la historia de la quimica. En 2019 se celebro, a nivel mundial, el 150 aniversario de la genial idea de Dmitri Ivanovich Mendeleiev de poner los elementos en una tabla periodica. El presente libro es un aporte mexicano, por demas original y ameno, a esa celebracion.

From the head of the University of Cambridges Institute for Manufacturing, an illuminating journey through the world of manufacturing and its transformational influence on our lives - and the world around us.SHORTLISTED FOR THE 2025 ROYAL SOCIETY SCIENCE BOOK PRIZE LONGLISTED FOR THE 2025 FINANCIAL TIMES & SCHRODER BUSINESS BOOK OF THE YEARRevelatory.SUNDAY TIMESFascinating.THE TIMESIntensely readable.IRISH TIMESWell-observed and enjoyably written.FINANCIAL TIMESAn extraordinarily good read.DAVID SPIEGELHALTER, author of The Art of Statistics***We live in a manufactured world. Unless you are floating naked through space, you are right now in direct contact with multiple manufactured products. How often do we stop to think: where do the things we buy actually come from?There exists a nearly invisible, awe-inspiring global system of manufacturing that enables virtually every aspect of our existence. The things we surround ourselves with take surprising and often byzantine journeys to reach us - be it the thousands of litres of water needed to make a single pair of jeans or the components of our smartphones travelling over six times around the world to reach us.From mega-factory floors, engineering laboratories and seaports to distribution hubs, supermarkets and our own homes, Tim Minshall traces these journeys to reveal the hidden world of manufacturing.Charting how this world came to be, Your Life is Manufactured reveals the seismic impact manufacturing has had on our lives and the natural world, exploring how it could offer us a path to a truly sustainable, more equitable future. In doing so, Minshall grants us the ability to make better choices for ourselves, our communities and the planet.***An illuminating and at times mind-boggling exploration of a global choreography that means I wont look at my kettle the same way again.ZOE LAUGHLIN, presenter of BBC Fours How to MakeThis brilliant book shows that manufacturing is foundational to our lives, not only now but also if there is to be any hope for a sustainable future. I learned something new on every page.PROFESSOR DIANE COYLE, author of Cogs and MonstersReading this book is like being given a personal tour of the worlds factories by a real-life Willy Wonka. Brimming with insight, curiosity and wit, Tim is a masterful storyteller of the manufactured world.DR ANNA PLOSZAJSKI, author of Handmade: A Scientists Search for Meaning Through Making
