be able to achieve 100% of the product because there are always ways that some of the product residue can be left over on the sides of the funnel or the sides of the beaker. 2) If you receive more than 100% yield, it means something went wrong. The precipitate could have not dried completely when the mass was taken or the filter paper mass could have been affected by the tear put in it when making the funnel. 3) It is important to know the true percent yield of any reaction because then you will be
12/7/14 Chemistry Period 8 Title: Calorimetry Lab Research Question: To measure the amount of energy stored in a peanut. Introduction: The term energy means the capacity to do work. Many different things have a different amount of energy (the capacity to do work). A peanut is one of these items. Peanuts
Goals: 1. The central goal of Project 3 is to synthesize biodiesel from natural products such as vegetables oils and other chemicals such as solvents and bases. Being able to synthesize biodiesel will allow us to understand the fundamentals and mechanics of the different components used in the production of biofuel. 2. Once the biodiesel is synthesized, it must be tested. The importance of testing the biodiesel is to determine whether it can be used as fuel by testing different properties of

NO THANKSUSE THE APP Research paper Abstract This experiment was conducted in order to determine if in fact a goldfish, an animal in which is classified as an “ectotherm” is affected by the temperature change of its habitat according to the lab text. An ectotherm is an animal that uses the environment in order to regulate its own body temperature, this experiment will have students with the
If the HCl were to be added to the solution too fast, then splattering would result which could potentially cause harm. Also, an exothermic reaction results when acid is being added to the solution because it is very reactive. The slow addition allows for there to be control over the reaction. The swirling action during the small additions of acid is needed in order to ensure a complete reaction with the mixture to produce
CHAPTER 3 MATERIALS AND METHOD In this research, the materials will be used are Zn Plate (99.9% purity, Merck), Potassium Hydroxide (Merck), Commercial Zn Plate (Energizer) and diesel oil. Water that will be used is distilled water. 3.1 Preparation of Zinc Plate 3.1.1 Pure Zinc The sample of Zn is taken from the other place. Before proceeding to the next step, the bulk of the Zn will be cut into dimensions 1 cm. After that the sample will be experienced grinding process. The purpose of the grinding
repeated to make successive dilutions from 1ml of urine from the specimen taken before. Figure shows the flow chart of this project. From the figure, it shows that the initial step to start this project was to do literature review about earlier research or article related to the topic. This is as preparation before start
Alcohol: Taken 10 gms of leaf powder and added 50ml of ethyl alcohol stirred it constantly for 30 minutes and the solution was kept at room temperature for 24 hours (minimum) and then filtered. The filtered solution is again filtered with watman filter paper No.3 and then it was stored at 4 degrees centigrade (in a freezer) until use.

the interior of the leaf, which changes the buoyancy causing the disks to rise. Since cellular respiration is taking place at the same time, consuming oxygen, the rate that the disks rise is an indirect measurement of the rate of photosynthesis. Research Question How do different wavelengths of light affect the rate of photosynthesis in which spinach leaf disks rise? Hypothesis I believe that the rate of photosynthesis of the leaf disks will be white, blue, and red, from highest to lowest in that
