Experiment 2: Laboratory Techniques and Measurements Course Number: CHE 111 Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel‚ which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric

The results provide evidence that when there was an increase in the sodium chloride concentration the mass of the potato prisms declined. At the zero percent concentration there was an increase of mass by 1.75%‚ from there the 1%‚ 3%‚ 5% and 10% begun on a downward trend with the percentage change in mass declining. The graph was on a steady decline from 0% being the highest point with a change of mass of 1.75% finishing with the 10% solution on a decline of -12.28%. From observing the scatter plot

Experiment 2: Intermolecular Forces Performed: 9/12/2011 Submitted: 9/20/2011 Chemistry 1046L PART I: Purpose: The purpose of partI in this experiment is to identify a variety of unknown substances’ properties using observations of the temperature changes that occur during evaporation. We know that substances with weaker intermolecular forces‚ such as London dispersion‚ will have a faster vaporization rate and thus a higher temperature difference compared to

I hope this is what you are looking for... good luck with it. A.) --WATER FLOW IN PLANT: Can water travel through plant stems? MATERIALS: graduated one liter bottle‚1 white carnation with long stem‚ 2 glasses‚ red and blue food coloring PROCEDURE: 1. Pour 500 ml of water into each glass. 2. Add three or four drops of food coloring to each glass. Be sure the color is dark. Add more food coloring if necessary. 3. Very carefully cut the stem in half along the length of the stem from the bottom

ntroduction: Cells have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic

The salago plant can be found all over the country and is known by different names and species. The plant is called “baleo”‚ “tuka”‚ or “dapnit” in the Ilocos provinces; “salago” or “taho” in Albay; “titipuho” or “palipo” in Batanes Island; “salagip” in Batangas; “sagu” in Laguna; “salago” or “siapo” in the

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the
