Using hydrogen bonding and surface tension, explain how the lab worked. To conduct lab, we used penny and water. There is hydrogen bonding between positive and negative charge of different molecules. Due to the strong bonding, 31 water droplets connects with each other by hydrogen bonding. While surface tension is the force that connect the water molecules on the surface. After 31 drops, any additional drop on penny didn’t stay on it.

Using the internet,look up the density of liquid water, ice, and ethanol. Using those values, explain your results. density of water - 1 density of ice - 0.9 density of ethanol - 0.7

To conduct this lab, we used beaker with water, beaker with ethanol, and salt. Water dissolves more substance than any other liquid because of its polarity. When we added salt in a water, most of the amount dissolved in a water, while very less amount remain undissolved and settled at the bottom of the beaker. Ethanol cannot dissolve some of the substances, because it is non-polar in nature. Therefore, when we add salt in ethanol, most of the amount remain undissolved and only fewer particles dissolved in the solution. Using your knowledge of specific heat, explain why there is a difference in time between the two solution.

To conduct this lab, we used beaker filled with water and ethanol. Specific heat defined as the amount of heat use by a substance to increase it temperature by 1 degree celsius or the amount of heat that substance lose to decrease it temperature by 1 degree celsius. When we placed both beakers on the hot plate, the beaker which had water boiled faster than the ethanol because water absorbs energy before it begins to

Lucas Goldoni Essay

Lucas Goldoni Bio Honors Lab Report The Effect of Enzyme Concentration, pH, and Temperature on the Rate of Reactions Abstract: In the lab we submerged pieces of potatoes within different concentration of Hydrogen Peroxide solution, then changed the temperature of the enviorment, and finally changed the pH of the enviorment. The potatoes acted as the enzymes and the Hydrogen Peroxide solution acted as the substrate in our experiment. We discovered that the effects on enzymes changing these variables…

plant photosynthesis Essay

Lab Exercise DNA Extraction 10/30/13 DNA in all organisms is found primarily in chromosomes. Eukaryotic cells, like those found in humans, contain several linear chromosomes. Prokaryotic cells, such as bacteria, contain one large circular chromosome. DNA is composed of building blocks called nucleotides, each made up of a five-carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base. The four kinds of nucleotides differ only in their nitrogenous bases. It is…

Synthesis Of Geometric Isomers

Experiment 1 Synthesis of Geometric Isomers Techniques to review before coming to the laboratory: Appendix C: Vacuum filtration, Refluxing Type of Lab Report: Modified Formal, review Appendix A: Modified Formal Lab Reports, hand in at the beginning of your next lab. Introduction: Alkenes are hydrocarbons with a C=C double bond. The double bond is stronger than a single bond, yet paradoxically, the C=C double bond is much more reactive than a C-C single bond. Historically, hydrocarbons…

Supplemental Information For Rocketry Research Report

Supplemental information for Rocketry Research Report Why should we continue explore our universe? I believe we should continue to explore our cosmos to further gain knowledge on our world. Not only that but as intellectual beings we have the right to "discover" and "explore" to satisfy our curiosity, which is what led space exploration in the first place. The universe holds an infinite amount of resources and unknown materials that we couldn't possibly imagine, and in different ways this can…

Biology: Protein and Amino Acids Essay

Figure Two (www.studyblue.com) Secondary Structure The secondary structure is what happen when the amino acids begin to join together and fold. This is due to what is known as iconic bonding, a combination of metals and non-metals and hydrogen bonds. The resulting shapes can take two forms; α helix, which can be described analogously to a spiral staircase and β pleated sheet, similar to a sheet of cardboard with bumps across it. Figure three shows this.…

Inorganic Liquid Ammonia Essay

which is the necessary evidence to prove the formation of 1,2bis(diphenylphosphino)ethane. Introduction: In chemical laboratories, liquid ammonia can extensively be utilized as a nonaqueous solvent, as a medium for reductions. Since, liquid ammonia contains hydrogen bonding interactions it will have unusual properties that allow it to dissolve compounds not readily soluble in water. Anhydrous liquid ammonia, for example has the chemical properties to dissolve certain high reducing metals including alkali, alkaline and lanthanide metals…

Ozone Depletion Research Paper

Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth's stratosphere, and a much larger springtime decrease in stratospheric ozone over Earth's polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events. The details of polar ozone hole formation differ…
