Copper-iron stoichiometry lab report 10/3/12 abstract: the lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. Group # _____ name_____ stoichiometry air bag lab introduction: the airbag is now a common piece of safety equipment found in all new automobiles its development required the combined efforts of engineers and chemists. Normal community high school mission normal community high school was established in 1905 our continued mission is to establish a community of learners, pursuing excellence every day. Microsoft word - 8-23,24 stoichiometry labdoc author: brent white created date: 7/13/2005 11:38:34 pm.
Stoichiometry lab: the determination of the mass of product of a chemical reaction 2 2 using your bunsen burner, gently heat the beaker and its contents until all the liquid is driven off leaving behind. The molar masses of the substances and the reaction stoichiometry come into play also, so we can't automatically assume which substance is the limiting reactant until we go through the steps as we did above. This lab is adapted from: kristen l cacciatore and hannah sevian, teaching lab report writing through inquiry: a green chemistry stoichiometry experiment for general chemistry, journal of chemical education, 83(7), 1039, 2006. Stoichiometry lab report brittney aceron karla wadechoza, jonathan guerrero, luis martinez caroline chen stoichiometry lab report essay submitted by marylovesdante words: 1181.
This is the lab procedure in which students produce a calcium carbonate precipitate by reacting calcium chloride with sodium carbonate they then filter and dry the precipitate and weigh it to compare to a stoichiometric calculation. Stoichiometry lab report by: alex gamboa alicia adrian arturo scientists use stoichiometry to see how much gather information on how much of each element should be used in an lab. Purpose: the purpose of this lab was to use stoichiometry to determine some relationship between molarity and mass quantities it also assisted in the proper usage of the crucible and the analytical balance. The principles of stoichiometry and limiting reagents will be used to predict the amount of product that should be produced when mixing two solutions to produce an insoluble product. We used stoichiometry to calculate the grams of baking soda we were supposed to use, as well as predict the amount of products we would create pre-lab before we could do the lab we had to calculate many things.
This outcome-based lab requires the students to precisely predict the mass of the solid product an electronic balance will reveal how close the students come to their target and determines their grades. Stoichiometry limiting reactant objective: this experiment exams the idea of the limiting reagent through the stoichiometric relationship between reactants and products in a selective. Materials vinegar (5% acetic acid) baking soda (sodium bicarbonate) at least 7 small plastic cups (4-6 oz. Stoichiometry lab in class, you've learned to compute how much of a chemical product you can make when you mix measured amounts of chemical reactants in this lab, you.
Stoichiometry solve problems in chemistry using dimensional analysis select appropriate tiles so that units in the question are converted into units of the answer. Stoichiometry lab i statement of purpose the purpose of this lab was to determine the mass and mole relationship among the products and reactants for the reaction of copper with silver nitrate. 5 determine the limiting reagent and calculate the theoretical yield of a reaction 6 calculate percent yield prior to lab read the sections of our textbook that address the topics: stoichiometry.
First, the barometric pressure in the lab will be provided by the instructor the eudiometer is inverted in a beaker of eater and contains hydrogen gas above the acid solution the barometric pressure is the pressure at the level of the water in the beaker. Day 11 - stoichiometry fireworks lab quiz students may choose to have randomly assigned groups of two or work with their regular lab partner (the whole class must do the same thing) students may choose to have randomly assigned groups of two or work with their regular lab partner (the whole class must do the same thing. Aluminum metal reacts with hydrochloric acid to form hydrogen gas and an aluminum chloride solution in this investigation, you will predict the mass of hydrogen gas produced by a given amount of reactants, then measure the amount, and compare them.
Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients do the same with chemical reactions see how many products you can make with different amounts of reactants. In this lab, students will perform a simple chemical reaction in a closed system to produce a small amount of gas they will collect mass measurements for the reactants and the products in order to demonstrate the conservation of mass during the reaction. Transcript of stoichiometry lab presentation procedure results proving stoichiometry according to stoichiometry the moles of iron to copper could be: 1:1 ratio 2:3 ratio 1 make. Post-lab questions: top based on your experimental data, does the stoichiometry of a product of a chemical reaction depend upon the amounts of reactant available to form the product cite experimental evidence to support your answer.
