Welcome!
Hello JulianaPacheco, welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Our intro page contains a lot of helpful material for new users—please check it out! If you need help, visit Questions, ask me on my talk page, or place   on this page, followed by your question, and someone will show up shortly to answer your questions. I had to undo both of your two edits, however, as they were completely redundant with what was already in the articles, and were mixing up different topics among the sections. In addition, the antiacid content had some chemical mistakes--it's not uncommon that student study-guides are only "correct" in a limited context or only tell an incomplete story:( DMacks (talk) 04:17, 1 December 2012 (UTC)

Hello, I'm Materialscientist. I wanted to let you know that I removed an external link you added to the page ethanol, because it seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.
