CHEM111AC‚ Experiment#9 - Ionic Reactions Discussion/Error Analysis In the first part of this experiment‚ the student was presented with 7 unique and unidentified bottles of solutions labeled A-G and was expected to be able to analyze the 7 solutions through trial and error and mixing them with one another. For solution A: mixing A + B formed a precipitate‚ A + C generated heat‚ A + D gave no reaction‚ A + E gave no reaction‚ A + F gave no reaction‚ A + G formed a precipitate. For solution B: mixing

Molecule Polarity PhET Lab A study of electronegativity‚ bond polarity‚ and molecular polarity Introduction: In this atomic-level simulation‚ you will investigate how atoms’ electronegativity value affects the bonds they produce. When two atoms bond‚ a pair of electrons is shared between atoms. Electronegativity is a measure of a single atom’s ability to hoard electrons shared in that bond. In this lab you will work diligently‚ at your own pace‚ to answer a number of questions. To begin‚ from

science which is boring; requiring intensive memorization and less logical reasoning. True to my heart‚ my view towards biological science was no difference! It was not before my higher secondary school classes when I first realized the beauty of this scientific arena. I had my first glimpse at molecular biology then. But that brief introduction to molecular biology was enough to compel me to the idea that I want to spend my whole life working and conducting research on it. That passion and zeal brought

I. Purpose The purpose of this lab is to determine the molecular mass of a volatile liquid. II. Procedure • Place a cork with a small hole in it inside of a test tube and find the weight of the two together using a sensitive balance. • Pour 0.5 mL of the unknown volatile liquid into the test tube‚ insert the cork‚ and place the tube into boiling hot water while keeping the cork above water level. As the gas evaporates‚ excess gas will be released throughout the whole in the cork. Keep the test

Ultra thin film coatings can be used in a wide range of applications as lubricants‚ anti-stiction layers‚ molecular glues‚ coupling agents or adhesion layers. The mentioned molecular coatings are used to modify material surface properties. The traditional coating deposition methods consist of a set of sequential wet baths. The wet processing method is complex and limits the ability of molecular coating in many MEMS applications. The use of liquid precursors has extremely limited bath life‚ which cause

similarities as well as differences. From 750 to 30 B.C.E.‚ the Greeks created impressive temples‚ stoas (covered colonnades)‚ theaters‚ and amphitheaters. The temples‚ built in marble and limestone‚ retained the post-and-lintel construction of the wooden originals. The temples had painted decorations and low-pitched wooden roofs. Columns had ornamental capitals—the top of the column—in one of three designs. The simplest‚ Doric‚ consisted of columns with plain molded capitals and no base. Ionic capitals were
