Download file to see previous pages This paper details the results of an experiment to produce zinc iodide from the reaction of zinc with iodine, making use of the laboratory setup given to investigate aspects of the reaction relating to the conservation of mass, the identification of the limiting reagent, and the observations on the physical characteristics of the solution as it underwent the reaction Spatafora, 2010; Nuffield Foundation, 2013. Which type of compound usually has higher melting points, ionic compounds or covalent compounds? This was done through five chemical reactions involving copper. . We heated the substance again to remove any excess water. As you progress further in science, you will see variations in styles of lab reports, though they all contain the same basic principles. As a student, you will be asked to write reports to show that you have investigated or researched a particular problem. Figure and table titles may be single spaced.

Lab reports are to be computer-generated and double-spaced. In the second experiment, students are asked to identify a white precipitate that forms during a synthesis of zinc iodide from its elements when a specific reagent, acetic acid, is not used. Zinc is a metallic element which is an essential product required by our body. It reacts and dissolves, giving off a colourless gas hydrogen. Students utilize stoichiometry, barometric pressure calculations, the ideal gas law, and a variety of chemical techniques, such as the collection of a gas over water, to solve this problem.

Hypothesis: Yes, I believe it is possible to determine if this reaction took place by using the oxidation numbers in the equation. To examine a variety of reactions including precipitation, acid-base, gas forming, and oxidation-reduction reactions. The report is due at the beginning of Lab 11 Cell. Synthesis Scenario Auditory James should use Socratic learning method, where he should ask his what they know about symbolism, metaphor and simile. Visual Visual tools can enhance and aid James in teaching, as then he can invite the students to participate in the lecture, which would keep them alert to the auditory environment as well. T Empirical Formula of Magnesium Oxide: Lab Report The objective of the experiment is to determine the empirical formula of Magnesium Oxide through a procedure of heating magnesium ribbon to react with oxygen to form a magnesium oxide compound with the correct ratio of atoms within each element; 1:1. All sections of the report must be written in paragraph form.

Experiment, Laboratory, Logic 1036 Words 4 Pages lab reports becca Medina Biology Lab 1107 Lab Notebook The Scientific Method Problem: Will a male or female have a higher heart rate after participating in the physical activity of running up three floors of a building? The physical characteristics of the solution of zinc and iodine were observed and noted, especially with regard to the changing colors of the solution as the reaction progressed. Therefore, the combined mass of the beaker and Zinc was 60. The calculations of a stoichiometry problem depend upon balanced chemical equations. James must draw as much information from them as possible, filling gaps with his own expertise. The reaction can be easily reversed using electrolysis to decompose the compound back into its elements.
