My experiment in stoichiometry

Resource topic: stoichiometry the mole, molarity, and density autograded virtual labs creating a stock solution autograded virtual lab in this activity, students use the virtual lab to create dilute solutions from a concentrated stock solution of acids or bases. I thought my experiment was fair method because i have taken readings for 3 times for results which shown different results and have taken 2 readings for the results which are the same for different number of pieces. Chem 1105 experiment 7 1 experiment 7 - reaction stoichiometry and percent yield introduction stoichiometry calculations are about calculating the amounts of substances that react and form in a. Students use stoichiometry and thermochemistry to design a new fuel for a mission to mars in this activity, students work in teams using the virtual lab to characterize a new set of oxidants and reductants that.

my experiment in stoichiometry To determine the limiting reagent in a reaction through a measured quantity introduction in this lab, you will be investigating reaction stoichiometry by doing a series of mixing experiments using acids and bases in different amounts.

In this particular lab we used stoichiometry, the part of chemistry that studies amounts of substances that are involved in reactions, to observe the reactions made by combining sodium hydrogen carbonate, nahco3, (baking soda) and acetic acid, ch3cooh, (vinegar) together we also had to predict the amount of carbon dioxide, water and sodium. Stoichiometry expresses the quantitative relationship between reactants and products in a chemical equation stoichiometric coefficients in a balanced equation indicate molar ratios in that reaction stoichiometry allows us to predict certain values, such as the percent yield of a product or the molar mass of a gas. In this experiment you know the concentration and the volume of the two solutions that you mix therefore you know the moles of na 2 co 3 and the moles of cacl 2 that are reacted. This experiment is best done in groups of two students should have learned how to do stoichiometry problems, be experienced in using a balance, and be able to follow basic directions.

8 the waste from this experiment may be disposed of in the sink 9 analysis: experimental mole-to-mole ratios - convert the initial mass of sodium bicarbonate (or carbonate) reactant to moles (via its molar mass) in a similar manner, convert the final mass of collected sodium chloride product to moles (via its molar mass. View lab report - stoichiometry from chemistry 104 at portland community college lab report for experiment #10 stoichiometry of a precipitation reaction student's name _kaci ruby_ date of experiment. Lab stoichiometry john smith 3/4/13 b-3 stoichiometry relationships in reactions lab purpose: to compare the experimental mass of a product of a chemical reaction with the mass predicted for that product by calculation.

Iowa state university's professor tom greenbowe shares many simulations and animations in ten major areas of chemistry, such as gas laws, stoichiometry, kinetics, and more virtual chemistry experiments. The lab procedure that my class used can be found in the photo attachment the purpose of the lab was to determine the equation for the decomposition of sodium bicarbonate. Most students, and many of my (now former) colleagues, find stoichiometry to be one of the most challenging topics in a first year (and yes, even a second year) chemistry class but my students and i have always looked forward to the challenge, and the fun.

My experiment in stoichiometry

This lab is designed to provide data which demonstrate the validity of the mathematical techniques of stoichiometry by both calculating the amount of caco 3 that forms and measuring it in the lab it will be possible to calculate the percent yield for the reaction. Stoichiometry problem where we find the limiting reagent and calculate grams of product formed created by sal khan watch the next lesson: . Experiment and observations: as i performed the lab, i had to retrieve all my equipment's from my labpaq as i started to setup, i had to weigh out 10 gram of cacl22h2o on the digital scale after it was weighed, it was added to the 100 ml beaker and 25 ml of distilled was added and stirred.

  • In the first day students design their lab, which includes solving a stoichiometry problem on the second day they conduct the lab, and on the third day they write and critique their lab report in this lesson students learn how to design an experiment in which they can evaluate how closely an experiment's actual yield corresponds to the theoretical yield.
  • 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.
  • Experiment 7 investigating stoichiometry with sodium salts of carbonic acid introduction in this experiment we are going to get a better understanding of chemical stoichiometry we are going to be reacting sodium bicarbonate (nahco3) and sodium carbonate (na2co3) with hydrochloric acid (hcl.
