Before you put a coefficient of 2 in front of the oxygen on the product side, you must know whether carbon or oxygen is a diatomic element. I let them know that they can work on finishing previous stations information, such as classifying reaction, from the data that was collecting.
Decomposition reactions will have one reactant, whereas synthesis reactions will have one product. The only time that you can add a subscript in an equation is when there is a diatomic element.
They should recognize that it only has one reactant. Therefore, you will need to add a subscript of 2, not a coefficient of 2 to oxygen.
I also tell students that must remain at the lab station till time is given. Next time I perform this activity I will treat it more as a reinforcement lab than a assessment.
Chemical elements whose stable form at STP consists of diatomic molecules. 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.
There is a redistribution of charge when metals and nonmetals are charged e.
Students will have to look at the formula given to determine which copper ion to use. During the time at each station should need to accomplish the task that is written on each instruction sheet, write down the chemical equation, take notes, provided evidence for a chemical reaction and clean up the station see student work.
I only took one day to do this lab and I think it could have been spread out into two days by giving students a longer opportunity at each station. Once you have reviewed writing and naming ionic compounds, you are ready to begin the lesson on predicting products.
Please record the definition of this in your notes. Students spend approximately 4 minutes at a station before told to move the next station. 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.
This lesson works through each type of reaction as a means to understanding the products. The balanced reaction looks like this. They will use it to determine how the reaction will progress. 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.Oct 17, · Equation Writing And Predicting Products Lab Answers Writing and Balancing Reactions Predicting Products - Duration: Marc Seigelviews.
Writing chemical equations. Predicting The Products Of Chemical Reactions And Writing Equations Lab Answers - In this site is not the similar as a solution directory you buy in a photograph album growth or download off the web.
Predict the product(s) along with the states, indicate the type of reaction, and balance the following chemical reactions. a. A solution of lead (II) nitrate is mixed with a solution of sodium iodide. b. Solid zinc sulfide reacts with oxygen in the air. c. Liquid butane (C4H10 (l)) is used as a fuel to ignite a lighter.
d. In this lesson, students will be able to look at chemical reactions, both on paper and in a lab setting and predict the products of the reaction.
This is the last step in the process of writing a chemical equation. Students will: predict the products of the five basic reaction types. write correct formulas for the reactants and products. Predicting Products of Chemical Reactions This worksheet is designed to help you predict products of simple reactions of the four basic reaction types (synthesis, decomposition, single replacement, and double replacement) and combustion reactions.
