Title: Lab #3 Separation of a Mixture of Solids Purpose: To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment‚ I will separate a mixture of four distinct substances: sodium chloride‚ benzoic acid‚ silicon dioxide‚ and iron fillings into pure beings. Procedure: Materials: distilled water coffee

1. The first Skills Lab was designed in order to introduce us to the course‚ prepare us for working in teams‚ and for preparing us for success in this course and our future engineering courses. During this lab we were able to see the importance of teamwork in engineering and learn the names of those we will be working with in this course. We discussed the norms of being on a team and how we must work together to complete our goals. Along with how we must work together in teams we learned how to avoid

Heather Crall Chemistry 1 SMT- 271044 10/17/2012 Abstract From seeing all of my results and conclusion I now see that I didn’t understand this lab very well and that its not easy when others try to help. Since I have hard water it tells me that my water flows over and through rocks and minerals‚ like limestone. Purpose The purpose of this lab is to become familiar with the concept of water hardness. We learn that hard water contains high levels of dissolved minerals that are in the form
