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>

Good course, the right level for me to complete and learn the basics. I feel I've learnt a lot and worked hard.\n\nI found the calculations frustrating.
por SHJan 29, 2020
Really great course! I have learned so much over the past few weeks. I would recommend to anyone that needs to freshen up their chemistry skills.
por TASep 16, 2017
Skillful Quiz, the best understanding of chemistry. Although a little difficult to pass, U will be proficient in Introductory Chemistry.
por AANov 1, 2019
It was very good and helpful to me in many ways. It was so lovely to learn from her that i truly enjoyed learning .
por MAug 14, 2017
All the topics are very good. But in quiz part, some questions (especially choices) are not given appropriately.
por IGSep 7, 2019
Fantastic and challenging. But to God be the glory. And its a course a scientist should take on. Love it.
por LSep 15, 2017
Excellent presentation of the topics, easy to understand the instructor.
por ZANov 18, 2019
Perfect course and wonderful content and instructor.
Perguntas Frequentes – FAQ
Quando terei acesso às palestras e às tarefas?
Ao se inscrever para um Certificado, você terá acesso a todos os vídeos, testes e tarefas de programação (se aplicável). Tarefas avaliadas pelos colegas apenas podem ser enviadas e avaliadas após o início da sessão. Caso escolha explorar o curso sem adquiri-lo, talvez você não consiga acessar certas tarefas.
O que recebo ao adquirir o Certificado?
Quando você adquire o Certificado, ganha acesso a todo o material do curso, incluindo avaliações com nota atribuída. Após concluir o curso, seu Certificado eletrônico será adicionado à sua página de Participações e você poderá imprimi-lo ou adicioná-lo ao seu perfil no LinkedIn. Se quiser apenas ler e assistir o conteúdo do curso, você poderá frequentá-lo como ouvinte sem custo.
Qual é a política de reembolso?
Existe algum auxílio financeiro disponível?
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.
