Chemistry Article Portfolio
You will be reading ten articles about recent events/advancements in chemistry. For your portfolio, you will include a copy of each article, and a summary of the article. You must type your questions and responses to the questions for each article. I have selected the first articles for you, but the last articles you will choose.
