Lab 25 equation writing and predicting products answers to guess

Therefore the balanced reaction will be: 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.

Write the balance equation for this reaction, including the state of matter for each reagent. This means that oxygen is unstable alone and will be found in nature as a pair. Remind them to look for diatomic elements.

Once you have reviewed writing and naming ionic compounds, you are ready to begin the lesson on predicting products. Decomposition reaction Calculate the mass of each product. When you write the new products, write the cation first and the anion second and then neutralize the compound if needed.

They are closely related in terms of how you will predict the products of the reaction.

Now It's Your Turn to Identify the Reaction

Knowing that every ionic compound is made from a cation and an anion metal and nonmetalyou will form new products with the ions you have. It is not balanced.

This can very easily over looked but can make the difference between confusion and a successful lab. As explained in the previous section the stations are set up around the room into a separate stations. I let them know that they can work on finishing previous stations information, such as classifying reaction, from the data that was collecting.

The charges are shown so that you can see how they are redistributed. Composition reaction Calculate the percent yield of the product.

The balanced reaction looks like this. Before starting the lab I demonstrate the pattern that will be followed. Combustion reaction What is the percent composition of methanol? Types of Chemical Reactions Lab Demos students This is initially a lot for students to do in a 4 minutes, but after 2 stations they get the hang of the procedures and complete the task in the allotted time.

Chemical elements whose stable form at STP consists of diatomic molecules. Which natural law applies? The percent yield is low because the reaction was not complete; I still had some magnesium left and I probably lost mass while measuring the mass of the magnesium after the reaction.

Students spend approximately 4 minutes at a station before told to move the next station.PREDICTING PRODUCTS AND REACTANTS INTRODUCTION In this lab several different types of chemical reactions will be studied and, from the type of reaction, the product(s) can be predicted and in one case, a reactant will be.
