Introduction

<p>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. </p><p>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!</p><p>Prof. Canelas</p> ...

Matter and Energy

<p>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.</p><p>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.</p>...

Chemical Composition and Reactions

<p>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.</p><p>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.</p>...

Great Beginner Course. There are some parts where there will be frustration, but the forums are helpful. Any type of class involving math and science involves practice and work. Professor is great!

von PFNov 24th 2016

A very good course to review basic college chemistry, or to prepare for for taking a college course if High School chemistry was taken too long ago. Highly recommended!

Häufig gestellte Fragen

  • Sobald Sie sich für ein Zertifikat angemeldet haben, haben Sie Zugriff auf alle Videos, Quizspiele und Programmieraufgaben (falls zutreffend). Aufgaben, die von anderen Kursteilnehmern bewertet werden, können erst dann eingereicht und überprüft werden, wenn Ihr Unterricht begonnen hat. Wenn Sie sich den Kurs anschauen möchten, ohne ihn zu kaufen, können Sie womöglich auf bestimmte Aufgaben nicht zugreifen.

  • Wenn Sie ein Zertifikat erwerben, erhalten Sie Zugriff auf alle Kursmaterialien, einschließlich bewerteter Aufgaben. Nach Abschluss des Kurses wird Ihr elektronisches Zertifikat zu Ihrer Seite „Errungenschaften“ hinzugefügt – von dort können Sie Ihr Zertifikat ausdrucken oder es zu Ihrem LinkedIn Profil hinzufügen. Wenn Sie nur lesen und den Inhalt des Kurses anzeigen möchten, können Sie kostenlos als Gast an dem Kurs teilnehmen.

  • 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.
