This is an introductory course for students with limited background in chemistry; basic concepts involved in chemical reactions, stoichiometry, the periodic table, periodic trends, nomenclature, and chemical problem solving will be emphasized with the goal of preparing students for further study in chemistry as needed for many science, health, and policy professions.

Duke University has about 13, undergraduate and graduate students and a world-class faculty helping to expand the frontiers of knowledge. The university has a strong commitment to applying knowledge in service to society, both near its North Carolina campus and around the world. Over the seven weeks of Introduction to Chemistry: Reactions and Ratios, you will be able to progress from a most basic knowledge of matter and energy to solving interesting real world chemical reaction stoichiometry problems.

Each lesson in the course introduces some new concepts that allow you to build upon the material from previous lessons, so completing the coursework in the order that it is delivered will be most beneficial for developing a thorough understanding of synthesized information. This course is intended for students with very little background in the subject, but a strong foundation in algebra is needed to solve some of the problems.

In the first unit, the course will first introduce the basic concepts of scientific methods and measurement. Then we will talk about matter, energy, and stoichiometry. Last, we prepared several lab demonstrations by Dr. Ken Lyle. I hope that you are as excited as I am to what does positive and negative equal amazing world of chemistry!

Good luck! We will discuss the sub-atomic particles that govern chemical reactions, isotopes, anions, and cations. We will learn how to name compounds, calculate formula masses, convert between grams and moles, what percent of throat cancer is caused by smoking periodic trends, and more!

You can still earn a regular verified certificate without completing the advanced problem sets, so please be sure to keep working on the normal weekly exercises. Great work on watching videos, posting on the discussion forum and submitting your exercises! This week will be filled with introductions to chemical compositions, chemical reaction terminology, and reaction calculations. How much sodium is in my diet? What amount of pollutants are in drinking water? How much iron is in iron ore for steel production?

These of the types of problems you will be able to address this week. We are also going to learn the first type of chemical reaction equation in this course: Dissolutions. I hope this has been a rewarding experience for you because I know that the course is not an easy one and it is relatively long. So kudos to everyone who has made it this far! We will also practice combining what we know from previous weeks to complete reaction calculations.

Congratulations on making through to the final week of the course! It was not an easy journey for the past six weeks with dozens of videos, exercises, problem sets, and forum discussions. Kudos to the many of you who completed the honors lessons on top of the other work. I am proud of all of you! I really struggled with chemistry in high school, and this course is excellent! It helped me understand the core concepts of chemistry and I found it very enjoyable!

An exceptional course to revise previous concepts. The interviews and especially the practical videos were very enlightening. Strongly recommend this to people who lack backgrounds in what is honkai impact story or those who want to revisit knowledge they've not come across for a long time.

I learnt a lot! Thank you Professor Dorian A. It made me much more easier to understand what is a database management system pdf basic principles of chemistry and it builds me a lot what is the meaning of composition stoichiometry in chemistry confidence in answering some of the problems in chemistry.
