Banana Oil Lab Report Jesse Bradford 7/10/14 MTWR Section Introduction In the banana oil lab we began with isopentyl alcohol + acetic acid isopentyl acetate + Water. We needed for this experiment a hot plate‚ clamps‚ pipette‚ 5mL vial‚ caps‚ hoses and a thermometer. Upon starting‚ our group set up an open system experiment that allowed gases to be released to avoid pressure build up. We mixed together to molecules‚ 1.0mL of isopentyl alcohol‚ 1.5mL of acetic acid

Alka-Seltzer Rocket Formal Lab Report Abstract In the Alka-Seltzer Rocket lab one was to experimentally determine how much (grams) Alka-Seltzer and water in mL‚ is needed to launch the rocket the highest/longest distance in cm. Also to experimentally determine the % NaHCO3 in the tablet using the information from the highest/longest distance. Calculate the error and % error of NaHCO3 in an Alka-Seltzer tablet and to determine the limiting reagent for the highest/longest distance traveled. Alka-Seltzer

Michele Baden Bio 100 – 05 ALLELOPATHY INTRODUCTION The purpose of this lab was to observe the effects of chemical warfare among plants. Plant seeds compete with other plants and seeds‚ for sunlight‚ and nutrients in order to germinate. In order to win dominance over other seeds‚ and reduce competition‚ plants produce and release a chemical in order to prevent other seeds from germination. This type of chemical warfare is referred to as allelopathy. Allelopathy exists in many parts of the plants

a toxic chemical produced by cells in the body‚ into water and oxygen (Cain and others‚ 2010). The oxygen can be observed as bubbles coming from the reaction site. Catalase is found in many living tissues of organisms‚ including chicken liver. The purpose of this experiment is to determine what changes in pH‚ temperature‚ and enzyme concentration have on the rate catalase works to break down hydrogen peroxide. If the pH‚ temperature‚ or enzyme concentration changes‚ then the reaction rate of catalase will either speed up or slow down

live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

which we will be doing in this particular experiment. Purpose Measure the melting points of pure benzoic acid and pure mandelic acid. Determine the eutectic composition and eutectic temperature of benzoic acid-mandelic acid mixtures. Indentify an unknown compound using mixture melting points. Introduction Energy is needed to be applied to a solid compound in order to changes its state point of a compound. The actual purpose of the experiment is to determine the measurement and the melting

9/23/12 Lab Report #1 Meter Reading Summary The objective of this experiment was to learn how to read different meters like the D.C. volt meter and the D.C. amperes meter. In all meters each big line is a major division and each little line in between is a minor division‚ and if there is a line smaller than the minor division lines then that would be a sub minor division. Each meter has a low‚ medium‚ and high range. For example on the D.C. volt meter the ranges go from top to bottom 150‚ 15‚

Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

Procedures: In the first lab‚ seven test tubes were attained and six of them were filled with the solutions that were listed (Na Pyruvate‚ MgSO4‚ NaF‚ Glucose‚ Water‚ and yeast suspension). The last test tube was filled with water. After they were filled with the solutions they were incubated at 37 degrees Celsius for about forty minutes. After the forty minutes passed take the test tubes and measure the height of the bubbles that formed in millimeters. For the second lab‚ attain three beakers‚
