دانلود Educator Chemistry Courses – دوره های آموزشی شیمی

شیمی (Chemistry) یکی از دانش‌های بنیادین است که به مطالعه و بررسی ساختار، خواص، ترکیبات، و دگرگونی ماده می‌پردازد و در بسیاری از رشته ها به عنوان یک دانش اولیه و پایه برای فراگیری محسوب می شود. موسسه آموزشی Educator مجموعه ای از بهترین آموزش های مرتبط با شیمی را در گروه های مختلف دسته بندی نموده و برای علاقمندان به شیمی (دانشجویان رشته شیمی) فراهم نموده است. برخی از این مباحث در حوزه شیمی عمومی، بیوشیمی، شیمی آلی و ... دسته بندی شده اند. در شیمی عمومی (General Chemistry) بیشتر به بررسی مباحث پایه و اصطلاحات رایج و ضروری برای کار در رشته شیمی آشنا می شوید. بیوشیمی (Biochemistry) یا زیست‌شیمی با ساختار و عمل‌کرد اجزاء سلولی مثل پروتئین‌ها، کربوهیدارت‌ها، لیپیدها، اسیدهای نوکلئیک، و انواع دیگر زیست‌مولکول‌ها سر و کار دارد. هدف زیست‌شناسی شیمیایی پاسخ دادن به سوال‌هایی است که از زیست‌شیمی ناشی می‌شوند.

شیمی آلی (Organic chemistry) زیر مجموعه ای از دانش شیمی است که درباره ترکیبات کربن یا مواد آلی سخن می‌گوید، عنصر اصلی که با کربن ترکیبات آلی را تشکیل می دهند، هیدروژن می باشد. در گذشته به موادی که ریشه گیاهی یا حیوانی داشتند، مواد آلی می گفتند اما امروزه مواد آلی را می توان از طریق روش های صنعتی و آزمایشگاهی و به کمک مواد معدنی نیز سنتز کرد.

General Chemistry: Balancing an entire sheet of chemistry equations, memorizing the Periodic Table, and answering tough vocabulary questions is much easier when you have a strong foundation in General Chemistry. Whether you are taking your first college chemistry course or still in high school, knowledge of chemical processes provides insights into a variety of biological and physical phenomena. These phenomena and more are explored in Professor Franklin Ow’s General Chemistry course.

In each of his lessons, Professor Ow explains concepts in easy to understand language and follows with plenty of examples you will likely see on homework and exams. Lesson topics include Stoichiometry, Gases, Acid Base Reactions, and Electrochemistry. Professor Ow obtained both his BS and PhD in chemistry from the University of California, Los Angeles. He currently teaches chemistry classes at three universities and has won multiple awards in his academic field.
