Joe Schmoe Period 3 March 8‚ 2013 Lab Report: Empirical Formula of Zinc Chloride (ZnCl) * Purpose The purpose of this experiment was to learn how to determine the empirical formula. Empirical means “based on experimental evidence.” * Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1.00g and 1.25g. As the reaction

following Aβ-injection [19]. 2.5. Behavioral test: Morris water maze (MVM) 2.5.1. Apparatus The Morris water maze test was conducted as described [20‚ 21]. The maze consisted of a circular pool (200 cm in diameter) filled with water (23±2°C) to a depth of 40cm. The circular pool divided into four arbitrary quadrants. A transparent Plexiglas platform (the only escapable thing from the water) 10cm in diameter was submerged 2cm underneath the water surface at the midpoint of one quadrant. There were many

nearest 0.001 g and record it in the data table in the back of the laboratory workbook. 3. Then we determined the volume of the unknown solid by water displacement. We first filled a 100mL graduated cylinder about 1/3 of the way with water and we recorded the volume to the nearest 0.1mL. We carefully slid the unknown solid into the cylinder with water. We then recorded the new volume and subtracted the two recordings equaling the volume of the unknown. 4. We then calculate the density by dividing

The purpose of the study was to determine the quality of the Ottawa River and identifying any human activities that may affect water quality by sampling for benthic invertebrates‚ measuring the water temperature‚ testing for pH‚ turbidity‚ dissolved oxygen‚ examining the odour‚ colour‚ and appearance of the water‚ the amount of grasses‚ shrubs‚ trees‚ and known uses of the waterway. Description: Various human activities that may affect water quality include municipal wastewater‚ urban stormwater

The Center for Disease control has estimated that illnesses directly resulting from food contamination cause approximately 76 million illnesses‚ 325‚000 hospitalizations‚ and 5‚000 deaths each year in the United States. The rise of food-related illnesses can be mostly attributed to increased eating out. Half of every dollar spent on food in this country is spend on food prepared outside of the home. As the amount of people involved preparing our food rises‚ so does the risk of contracting an illness

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Pennsylvania State University Lab Report on Experiment 10- The Chemistry of Natural Waters Introduction What is water hardness? Water is extremely important to all living things and even to non-living things‚ indirectly. Therefore‚ the way water travels and gets to a place is also extremely important because its transportation methods determine the chemicals that get involved and added into the water as it travels. This relates to the hardness of water. The hardness of water is basically caused by the
