Chemical Reaction Types - Questions

The Chemical Reaction Types Concept Builder is comprised of 39 questions. The questions are organized into 18 different Question Groups and spread across three different activities. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

There are three activities in this Concept Builder. Those three activities are described as follows:

Reaction Type Fundamentals: Question Groups 1-8 ... Students are presented with a skeleton equation. They must enter coefficients in order to balance the equation. Each time a coefficient is changed, an Atom Count panel is updated. The panel shows the number of atoms of each element on reactant and product side of the equation.
Name That Type: Question Groups 9-14 ... Students are presented with three balanced chemical equations. By inspecting the equations, they must be able to identify the reaction type of each. They tap on a button to select their answers.
Wizard Difficulty Level: Question Groups 15-18 ... Students are presented with five balanced chemical equations, one from each reaction type category. By inspecting the equations, they must be able to identify the reaction type of each. They drag and drop a reaction type label onto the equation.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which difficulty levels are most appropriate for their classes.

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.
