Macroscopic patterns are related to the nature of microscopic and atomic-level structure. Introduction and Connection to the NGSS and Common Core In this lesson, students go through a series of lab stations in order to practice identifying reactions as chemical or physical changes and determining the physical and chemical properties that change during the reaction. At each lab station, students not only identify the signs of a chemical change, but they also read reactant and product descriptions in order to identify changes in chemical and physical properties that occurred. Each station is fun and allows students to get a real visualization of evidence that can predict a chemical change!
Chemical Reactions Having completed the prior unit on atomic structure and the naming of elements and compounds, the students are now ready to start looking at how atoms and molecules can rearrange themselves during chemical reactions.
The focus of this chapter is primarily on the basic mechanics of writing out and predicting the results of chemical reactions. Starting with the relatively simple synthesis and decomposition reactions, we work our way up through single replacement, double displacement, and combustion.
Students will need to copy of a periodic table and polyatomic ions reference lis t to be able to complete these worksheets.
All of the basic parts of a chemical reaction are covered by this worksheet. Students will identify the reactants, products, subscripts, and coefficients. Included is information on the state of matter notation that indicates whether each substance is a solid, liquid, gas, or aqueous solution.
Chemical reaction, product, reactant, subscript, coefficient, state of matter notation, solid, liquid, gas, aqueous solution, diatomic elements. Predicting the products and balancing chemical reactions is the main skillset that students need to have leaving this chapter.
I start teaching this with synthesis reactions, because they are one of the simplest and most straightforward forms of chemical reactions. This worksheet provides a few examples of how to predict products of synthesis reactions using oxidation states as well as showing students how to balance.
Chemical reactions, synthesis reactions, balancing equations, predicting products, oxidation state.
This worksheet is a good followup to the synthesis reactions worksheet, because all of the same rules and ideas apply, simply in reverse. I keep the problems in this assignment simple by either focusing on simple binary ionic compounds or giving students the names of the products in advance. Chemical reactions, decomposition reactions, balancing equations, predicting products, oxidation state.
Single-replacement reactions involve reacting a lone element usually a metal with a compound, resulting in the cations switching places. Students will learn to use the activity series for the first time as part of this worksheet, as they identify when reactions will and will not occur.
Students will need to copy of an activity series chart to be able to complete this assignment Essential concepts: Chemical reactions, single replacement reactions, balancing equations, predicting products, oxidation state.
Double-displacement reactions involve the switching of cations between two compounds. The prediction and balancing of these reactions isn't too much of a challenge for students at this stage, however, they now must consider whether or not each product will remain as part of the aqueous solution or will form a precipitate.
A simplified solubility table is included as part of this assignment. Chemical reactions, double-displacement reactions, balancing equations, predicting products, oxidation state, precipitate, solubility, aqueous solution.
Combustion reactions are the last type of chemical reaction covered, and for many students, one of the most difficult to balance. The products are always the same -- carbon dioxide and water vapor, but the coefficients for balancing these equations often become double-digits.
Chemical reactions, combustion reactions, balancing equations, predicting products.
