• Rate limited banned from websiteThese examples illustrate the ease with which the amounts of substances involved in a chemical reaction of known stoichiometry may be related. Directly measuring numbers of atoms and molecules is, however, not an easy task, and the practical application of stoichiometry requires that we use the more readily measured property of mass.

A simple decomposition reaction of sodium bicarbonate (baking soda) presents the opportunity for students to test their. knowledge of stoichiometry, factoring labels, and the mole concept. This outcome-based lab requires the students to pre-. cisely predict the mass of the solid product. Basic Stoichiometry PhET Lab. Let's make some sandwiches! Introduction: When we bake/cook something, we use a specific amount of each ingredient. Imagine if you made a batch of cookies and used way too many eggs, or not enough sugar. YUCK! In chemistry, reactions proceed with very specific recipes. The study of these recipes is stoichiometry. The Virtual Lab is an online simulation of a chemistry lab. It is designed to help students link chemical computations with authentic laboratory chemistry. The lab allows students to select from hundreds of standard reagents (aqueous) and manipulate them in a manner resembling a real lab. More information and offline downloads . Stoichiometry (#6-1) What is the relationship between Mass, moles and number of particles. Students can use linear relationships to relate moles and number of particles. StagedorkThe reaction can proceed in both the forward and reverse directions. When a system has reached equilibrium, no further changes in the reactant and product concentrations occur; the forward and reverse reactions continue to proceed, but at equal rates. A system at equilibrium is characterized by constant reactant and product concentrations, but ... As stated before, limiting reagents is a key concept within his lab as the reaction of Iron and Copper Sulfate can result in two different products through two different Equations [l] & [II]. It was up to the student to figure out which of the two equations pertained to the lab. Stoichiometry Theoretical Yield • The theoretical yield is the amount of product that can be made – In other words itʼs the amount of product possible from stoichiometry. The “perfect reaction.” • This is different from the actual yield, the amount one actually produces and measures Practice Problems: Limiting Reagents (Answer Key) Take the reaction: NH 3 + O 2 NO + H 2 O. In an experiment, 3.25 g of NH 3 are allowed to react with 3.50 g of O 2.. a. Which reactant is the limiting reagent?
