the electrons as a back donation to the pi orbital in DMSO. In the first experiment‚ I had to synthesized CuCl2~2DMSO to determine which DMSO atom; Sulfur or Oxygen‚ combined to Copper (II) Chloride. I was able to determine it base on finding the melting point and observing the Infrared Spectroscopy. Since copper is a hard metal‚ it will most likely bond to an oxygen atom because they are both hard. In the second experiment‚ I also synthesized RuCl2~4DMSO to determine which DMSO atom; Sulfur or Oxygen

Risk Taking Experiment A. There are many risks in life one must take. I had several options to explore for this experiment such as going on a drop roller coaster‚ sky diving‚ and killing insects. I thought that sky diving would be fun‚ but I am not old enough to do because the minimum age requirement was eighteen years old. I also explored the idea of killing insects especially spiders which I hate the most‚ but I thought going on a drop roller coaster would be more interesting. B. I chose the

An experiment by FACUNDO LOPEZ MENTOS GEYSER CARBONATED DRINKS AND MENTOS PROBLEM STATEMENT: WHAT IS THE EFFECT OF MENTOS ON CARBONATED DRINKS? BACKGROUND INFORMATION: The soda contain sweeteners (sugar or artificial sweeteners) flavoring‚ water and preservatives. Carbon dioxide (CO2) gas is added to the soda trough a high pressure process that causes the gas to dissolve into the liquid‚ when the soda is opened the gas is relieved

A minimum wage is introduced into an experimental labor market characterized by gift exchange. In the experiment‚ subjects are randomly divided into two groups‚ including manager group and employees group‚ with ten subjects in each group. In all periods each manager was matched anonymously with one employee no more than twice and never re-matched in two consecutive periods. In each period‚ the manager makes an individual wage offer to his matched employee and wage offers were written directly on

In the first experiment‚ the bacteria R. fascians and R. corynebacterioides grew equally well in all conditions of light‚ except ultraviolet light. We tested this by comparing the petri dishes to the petri dishes that grew without light. Here‚ the exposure time was constant for all the lights and no light‚ which is 48 hours. The light sources were different. However‚ none of the lights had an effect on the bacteria‚ for the bacteria just continued to grow normally. The only exception was that UV

Aim To find out how the permeability of a beetroot membrane cell is affected by ethanol. To do this we will investigate different concentrations of alcohol (10-70%) and measure the absorbance using a colorimeter to show us how much juice has leaked out. Hypothesis I predict that as the concentration of ethanol goes up‚ the permeability will increase as the ethanol will slowly dissolve more phospholipids (lipid bilayer) and so more anthocyanin (the beetroot juice) will leak out of the membrane

1. What police procedures are used during arrests‚ and how do these procedures lead people to feel confused‚ fearful‚ and dehumanized? The police used the art of surprise coupled with a lack of information during arrests. The shock of the abruptness of the arrests‚ public embarrassment‚ as well as being arrested at random times (especially in broad daylight) could all be labeled as contributing factors that would lead the people to feel confused‚ fearful and dehumanized. The behavior of the “prison

AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature
