Exercise 14: Qualitative Anion Tests PURPOSE: The purpose of this experiment is to identify some commonly occurring anions & to study some of the reactions used for their identification. PROCEDURE: You must first determine to which of the three groups the various anions belong. Since no two people observe the same event in exactly the same way it is important to also conduct specific confirmation tests on the known samples of each anion. This information will help identify the anion

An Introduction to Qualitative Analysis Purpose: Tests the ions of Mg2+‚ Ca2+‚ Sr2+‚ and Ba2+‚ and identify them separately. By using these observations‚ identify the unknown ion. Then tests the ions of SO42-‚ CO32-‚ Cl-‚ and I-‚identify them separately‚ and use the observation to identify the unknown. Procedure Part I - Qualitative Analysis of Group 2 Elements Mix 0.02M K2CrO4 with each Mg(NO3)2‚ Ca(NO3)2‚ Sr(NO3)2 and Ba(NO3)2 together. Secondly‚ mix 0.1M (NH4)2C2O4 instead

Facial Feedback Kendra Verlingo PSY/355 August 13‚ 2012 Denise Wiseman Facial Feedback The facial feedback hypothesis states that the action of a person’s facial musculature is a casual agent in the subjective sensation of emotions (Deckers‚ 2005).

For example‚ a smile from a person may cause

In this study‚ we found that the growth of the duckweed thalli did not have a significant difference in the NP solution and the creek water solution. Although we found that the duckweed grows faster in the NP solution‚ rather than the creek water they do indeed have relatively the same mean. Overall our results supports our hypothesis. This also makes us question what kinds of factors are affecting the creek water to kill off the duckweed. Duckweed also is known to stop the growth of algae‚ but in

The efficient-market hypothesis emphasizes that arbitrage will rapidly eliminate any profit opportunities and drive market prices back to fair value. Behavioral-finance specialists may concede that there are no easy profits‚ but argue that arbitrage is costly and sometimes slow-working‚ so that deviations from fair value may persist. Sorting out the puzzles will take time‚ but we suggest that financial managers should assume‚ at least as a starting point‚ that there are no free lunches to be

Hypothesis Statement Trees that exhibit gumming are more resistant to fusarium dieback caused by the polyphagous shot hole borer (PSHB) because the gum secreted acts as a defense against beetles that attempt to penetrate the bark‚ and as a result grant the tree faux resistance to the Fusarium euwallaceae fungi. Introduction Californian agriculture is at great risk because of a disease being spread by the Polyphagous Shot Hole Borer (PSHB)‚ Euwallacea sp. The PSHB is an ambrosia beetle
