PSY-310 Dr. Erica St.Germain SNHU Callous-unemotional traits and future offending Callous-unemotional (CU) traits are a known aspect of psychopathic personalities in adults. What this study sought to prove was that CU traits were a predictor of future criminal offending. Although prior criminal history is the greatest predictor of future offending‚ this study showed that self-reported CU traits in elementary age males are “a unique and robust predictor of future offending‚ even after controlling

Ocean County College Department of Chemistry Chem 180 Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced

Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was found to be 2.1726g which meant that through limiting reagent analysis Fe was determined to be the limiting reagent and the chemical reaction was determined to be as following:- CuSO4(aq) + Fe(s) Cu(s) + FeSO4(aq) Introduction: There were several purposes of this lab‚ the main ones were limiting reagent analysis‚ quantitative and analytical analysis

Hypothesis In this experiment the reaction equation will be: CuSO4?H2O + Ba(NO3)2 →Ba SO4+ Cu(NO3)2 In Lab#6 that we have done in Dec 15 2003; we have found out that the mole for hydrate in copper (II) sulfate is 5. Thus‚ by this experiment I will continue to use the answer that I have found in Lab#6. So by using the knowledge from Lab#6 the reaction equation will be: CuSO45H2O + Ba(NO3)2 →BaSO4+ Cu(NO3)2 We can measure the mass of copper (Ⅱ) sulfate and the mass of the barium nitrate. Thus
