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

antisocial behavior. The experiment was undertaken with pastoralists from southern Namibia and the study area is divided into two parts according to the exogenous differences in biomass production (a high yield and a low yield area). In this paper‚ biomass production is taken as a proxy of resource scarcity and moved the lab to the field to observe fundamental human behaviors‚ such as risk aversion‚ time preference‚ trust‚ spite‚ and cooperation. There were two experiments‚ such as‚ a one-shot public

Rock it out loud: discovering the location of harmonies that make your guitar sing. Purpose: To identify the locations of harmonics on an acoustic guitar and relate them to guitar string lengths. Hypothesis: If I pluck the sixth string of the guitar from frets nine- twelve‚ then those frets will not produce harmonics that are able to be heard clearly. Materials: Acoustic guitar ( adult or child sized) Cloth tape measure‚ metric Lab Notebook Procedures on finding harmonics on your

so the skeletal muscle cells are supplied with more oxygen and respiratory substrates used to generate energy in respiration where it is needed. A drug that increases heart rate is called a positive chronotrope‚ and this is demonstrated in this experiment when adrenaline is used to increase heart rate in Daphnia. One of the ways adrenaline increases heart rate is through the action of what is known as a ’second messenger ’ or ’transduction component ’‚ in this case it is a chemical made in the

The Rocky Shore Experiment Research Question: How does type of substrate affect the variation of species and vegetation as you move away from the seashore at a Rocky Shore? Hypothesis: As we get further away from the seashore‚ there would be a decrease in the number of species and vegetation found. Also‚ the type of substrate will have a major affect on the biodiversity. Background Information: A rocky shore is an intertidal area of seacoasts where solid rock predominates. Rocky shores are

EXPERIMENT 2: SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement

1. Animals Experiments were carried out in adult male Wistar rats (200-225 g; 2-2.5 months old)‚ obtained from Central Animal Research Facility‚ NIMHANS‚ Bengaluru. Adult rats were group-housed (3 per cage) in a climate-controlled vivarium with a 12:12 h dark/light cycle. All animals had free access to food and drinking water except during the stress procedure or behavioral evaluation. All the experiments were performed during the light phase between 10:00 h and-14:00 h. All experiments were approved

Knowing that calcium helps keep humans healthy and have stronger bones‚ I wanted to experiment how calcium might aid in the growth of lima beans. Background Information: In plant growth‚ calcium effects the metabolic process of other nutrient uptake that is vital for growth of the plant. Calcium also strengthens the cell wall structure (It is an essential part of the cell wall);

dominant thumb experiment is used to observe the correlation between handedness and thumb dominance and whether one inherited trait will always influences another correlated trait. Examples of this experiment of this can be traced back as far as 1908. In this experiment 50 people were asked to clasp their hands and the thumb dominance. Once the hands were clasped‚ one thumb would naturally overlap the other and the handedness of each subject was noted. The hypothesis of the experiment is that when
