Station 3 Write the balance equation for this reaction, including the state of matter for each reagent. After having many students struggle on this activity and not complete all portions of the lab report for each station, I decided not to grade it and thought it would be more beneficial to go over it as a class.
Now, your task is to predict what the products of those chemical reactions will be and write balanced equations. After performing this lesson for several years I have determined that this activity is very difficult for basic chemistry students, only having a limited amount of chemistry knowledge.
I find that it requires them to be able to synthesize a years worth of chemistry and apply it to a relatively new concept of predicting products.
We will work through all five reaction types and predict what the products will be. Before starting the lab I demonstrate the pattern that will be followed.
Lead Iodide is the precipitate. Combustion reaction What is the percent composition of methanol? Decomposition reactions will have one reactant, whereas synthesis reactions will have one product.
Decomposition reaction Calculate the mass of each product. The main goal of the last part of the class is to let students discuss the seven stations with their group and reflect upon their observations from each station.
The only time that you can add a subscript in an equation is when there is a diatomic element. As they sitting with their groups I am walking around helping students predict the products and looking to see who had difficulty determining the type of reaction. Please record the definition of this in your notes.
They will use it to determine how the reaction will progress. Chemical elements whose stable form at STP consists of diatomic molecules. They should recognize that it only has one reactant. On the front page students will see different ways to identify evidence of a chemical reaction.
Therefore the balanced reaction will be: When they form an ionic compound, it will be written as KCl. The equation is now balanced without adding any coefficients. Students spend approximately 4 minutes at a station before told to move the next station.
The balanced reaction looks like this. The charges are shown so that you can see how they are redistributed. Which natural law applies? When you write the new products, write the cation first and the anion second and then neutralize the compound if needed. Composition reaction Calculate the percent yield of the product.Chemistry Chemical Formulas and Equations.
Chemical Formulas and Equations a set of balanced chemical equations for all possible reactions in this lab. Types of Reactions and Predicting Products. Predicting Products. In a common synthesis reaction, sodium metal is lowered into a bottle of chlorine gas.
