Sujata Neupane Partner’s name: Samiksha Pathak Aryal Measuring Specific Heat Capacity of Unknown Metal The purpose of this experiment is to identify the unknown sample by calculating its specific heat capacity. 1. Introduction: Heat is a form of energy that is transferred between objects with different temperatures. The amount of heat released or gained by an object (q) depends on the mass of the object (m)…

Based on the experiment, it shows that the bromelain is started stable at 25% of enzyme concentration to 100% of enzyme concentration, pH 4 to 11, and the temperature range from 4oC to 37oC. For the concentration, it could happen because the presence of bromelain could break down the gelatin which makes the not solidified formation of the solution. In the temperature test, the lowest temperature makes the bromelain become optimum temperature which is regarded favorable for the digestive process,…

Exercise's Effects on Cellular Respiration Cellular respiration is a chemical reaction that creates energy through your cells. It requires inhaled oxygen and expels carbon dioxide. This carbon dioxide can be detected through the use of bromothymol blue (BTB), which is a pH indicator solution. When the carbon dioxide is exhaled into the solution, BTB reacts as it would with any other acid, and turns from blue to yellow. The higher the level of carbon dioxide, the more quickly the color changes…

Enzyme Post- lab assignment The purpose of this lab is to see the enzyme activity. We have known that biological chemical reactions are catalyzed by enzymes, so in the experiment 4.1 we tested the properties of catalase, and its presence in potato and sheep blood. The result was we could see the oxygen gas- bubbling by catalase’s presence. Not only that, enzymes are known as reusable, but they are not altered by their reaction with any substrate. In experiment 4.2, we could see that enzymes…

Reagents 2,4-dichlorophenoxyacetic acid (2,4-D) (Sigma-Aldrich), 2,4 dichlorophenol (2,4-DCP) (Sigma-Aldrich), ferric sulfate (nH2O) (Carlo Erba), hydrogen peroxide (H2O2) (Carlo Erba), acetonitrile (Sigma-Aldrich) and Milli-Q water were used to perform all the experiments . All the reagents were used without further purification. Natural groundwater samples Samples were taken from groundwater wells localized in a small rural community (coordinates: 3º21’03.38” N, 76º26’24.51”) near to the…

Calibration 1: Text Cyclohexane is a six carbon cyclic alkane that is unusually stable compared to other cyclic alkanes. This stability can be seen by examining cyclohexane in its chair conformation. Since cyclohexane consists of all sp3 hybridized carbons, it ideally exists with 109.5-degree bond angles. If cyclohexane were planar, it would be forced to have 120-degree angels, and would therefore have angle strain. However, cyclohexane chair conformations are almost completely free of angle…

Introduction The engineering case studies presented in the fictional video provides profoundly different sets of ethical issues that are presented at various manufacturing companies that want to put up hurriedly manufacturing chemical plants. Engineering profession, just like in many other professions is confronted with many ethical responsibilities. The study is exceptionally important to the practicing engineers since it presents viewers with ethical guidelines that should be followed when…

Introduction: Wind chill is the measure of the combined effect of wind and lowering temperatures on beings (Steadman, R. G. 1971). With wind chill animals would be cold especially during winter months with the harsh winds, because of this out in the environment animals have fur coats to help them hold and retain heat against the wind. The way animal is able to retain heat is due to thermal physiology designed to keep a being warm by preventing heat from leaving the body (Media 2014). An analysis…

Lithium is an element with the atomic number 3 on the periodic table. Its atomic symbol is Li. Lithium belongs in the most reactive group on the periodic table which is called alkali metal. Lithium under standard conditions is the lightest metal it is also one of the least dense solids. Lithium has an atomic mass of 6.94 and density of 0.534. Lithium is a soft silver white looking metal. Lithium melts at 357 degrees and boils at a temper of 2426 degrees. Thanks to lithium's ability to reach…

iv. Increased enzymatic capacities for substrate catabolism v. Higher degree of clustering of subsarcolemmal mitochondria adjacent to capillaries-> higher O2 flux rates vi. Mitochondrial volume densities and surface areas per unit mitochondrial volume are near maximum theoretical limits in hummingbirds and higher than mammals-> achieved due to higher oxygen delivery capacities and substrate catabolism (Suarez et al. 1991) 5. Metabolic Substrate Turnover a. Questions i. Do hummingbirds…
