Review Videos (I)

<p>Welcome! Over the eight weeks of the Introduction to Chemistry: Structures and Solutions course, we will begin discussions about the electronic structure of the atom, structures of molecules, phases of matter, and solutions. This week, we included some basic concept videos in Chemistry. These come from the partner course called Introduction to Chemistry: Reactions and Ratios. You can technically start with either course, but when these courses were originally designed, the Reactions and Ratios content came first, and you might find it helpful to complete that course before this course. If you are not familiar with the concepts of physical change v.s. chemical change, or significant figure and scientific notations, then please begin by reviewing video “Introduction”. I hope you enjoy this week's materials!</p>...

常見問題

  • 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.

  • When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.

  • 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.
