La química es la ciencia que estudia las propiedades y transformaciones de la materia. Todo lo que nos rodea está formado por compuestos químicos, cuyas propiedades, aplicaciones y transformaciones dependen de los elementos que los forman y de su estructura. Esta xserie va dirigida a los alumnos que acceden a la Universidad y que requieren conocimientos básicos de esta ciencia. La serie consta de ocho cursos en los que se tratan conceptos generales sobre la estructura de la materia, el enlace químico, la formulación inorgánica y orgánica, las reacciones químicas, los ácidos y las bases, las sales y sus propiedades, y las reacciones de oxidación-reducción y sus aplicaciones en la naturaleza y la industria.
An excellent online course offered by edX: how it works
edX courses consist of weekly learning sequences. Each learning sequence is composed of short videos interspersed with interactive learning exercises, where students can immediately practise the concepts from the videos. The courses often include tutorial videos that are similar to small on-campus discussion groups, an online textbook, and an online discussion forum where students can post and review questions and comments to each other and teaching assistants. Where applicable, online laboratories are incorporated into the course.
edX offers certificates of successful completion and some courses are credit-eligible. Whether or not a college or university offers credit for an online course is within the sole discretion of the school. edX offers a variety of ways to take courses, including verified courses where students have the option to audit the course (no cost) or to work toward an edX Verified Certificate (fees vary by course). edX also offers XSeries Certificates for completion of a bundled set of two to seven verified courses in a single subject (cost varies depending on the courses).
