Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

Experiment #2 “Density Determinations” Report The objective for experiment #2 was “to determine densities of objects/salt solutions with different concentrations of salt‚ to see how density changes as a function of concentration.” In experiment #2‚ part II‚ calculations of Density of NaCL solutions were made from 0%-25% NaCL concentration. My hypothesis was that as the % increased‚ so would the density‚ because adding weight would increase the density of each solution. The density calculations

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

Determining the Enthalpy of a Chemical Reaction All chemical reactions involve an exchange of heat energy; therefore‚ it is tempting to plan to follow a reaction by measuring the enthalpy change (∆H). However‚ it is often not possible to directly measure the heat energy change of the reactants and products (the system). We can measure the heat change that occurs in the surroundings by monitoring temperature changes. If we conduct a reaction between two substances in aqueous solution‚ then the

This paper is a full determination for certain chemicals and their boiling points. It lists some already but given the atomic numbers of any material this project includes a conversion and calculation chart to find the freezing point of most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step

Bilirubin is a breakdown end product of heme containing proteins. About 80% of bilirubin is formed from the degradation of erythrocyte hemoglobin after 120 days of erythrocyte life in the blood. The remaining 20% of daily-produced bilirubin is formed from erythrocyte precursors in bone marrow and other heme proteins: myoglobin‚ cytochromes‚ and catalase. Hemoglobin degradation begins with opening of the heme porphyrin ring‚ forming the biliverdin – iron – globin compound known as verdoglobin.

Free will Vs Determination Do you make your own choices or your destiny has been decided for you by circumstances behind your control? For thousands of years‚ this question has puzzled philosophers‚ scientist and anyone who thinks about how they choose to act and live. Part of the complexity of the matter is related to the metaphysical nature of the subject which has a close affinity with the concept of GOD. Some people think that "Everything" that happens in nature and life
