Introduction

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 this amazing world of chemistry! Good luck!Prof. Canelas ...

Matter and Energy

If you are interested in significant figures in more detail, here are some <a href="https://www.khanacademy.org/math/pre-algebra/decimals-pre-alg/sig-figs-pre-alg/v/significant-figures" target="_blank">good videos</a> to follow on Khan Academy.This week we will continue our explorations of matter and energy. 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, examine periodic trends, and more! An advanced problems set is posted now; that is a longer assignment and is optional unless you would like to be eligible for the Honor’s Track. 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....

Chemical Composition and Reactions

Week 4 for Introduction to Chemistry: Reactions and Ratios is about to begin! This week will be filled with introductions to chemical compositions, chemical reaction terminology, and reaction calculations.If any of the following questions interest you, then watching this week's videos and doing some practice problems are probably a good way to get started! 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....

Solutions and Solubility Rules

In the past five weeks of the course, we have learned concepts, rules, and skills, including but not limited to: the definitions of atoms, elements, molecules, and compounds; energy changes; Coulomb’s Law, molecular stoichiometry; atomic structures; periodic trends; the mole; compounds; atomic and molecular masses; molecular stoichiometry; balancing chemical equations.In this coming week, we will be discussing aqueous solutions, solubility rules, precipitations and electrolytes! We are also going to learn the first type of chemical reaction equation in this course: Dissolutions....

Acid-base and Redox Reactions

We are almost at the end of our course! 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!Week 6 for Introduction to Chemistry: Reactions and Ratios will include very basic introductions to acid-base and redox reactions. We will also practice combining what we know from previous weeks to complete reaction calculations....

Frequently Asked Questions

When will I have access to the lectures and assignments?
Once you enroll for a Certificate, you’ll have access to all videos, quizzes, and programming assignments (if applicable). Peer review assignments can only be submitted and reviewed once your session has begun. If you choose to explore the course without purchasing, you may not be able to access certain assignments.
What will I get if I pay for this course?
If you pay for this course, you will have access to all of the features and content you need to earn a Course Certificate. If you complete the course successfully, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. Note that the Course Certificate does not represent official academic credit from the partner institution offering the course.
What is the refund policy?
Is financial aid available?
Yes! Coursera provides financial aid to learners who would like to complete a course but cannot afford the course fee. To apply for aid, select "Learn more and apply" in the Financial Aid section below the "Enroll" button. You'll be prompted to complete a simple application; no other paperwork is required.
Will I receive a transcript from Duke University for completing this course?
No. Completion of a Coursera course does not earn you academic credit from Duke; therefore, Duke is not able to provide you with a university transcript. However, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
