Give your chemistry students a focused look at revising models when balance with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Sample questions include "In balancing the equation C₃H₈ + O₂ → CO₂ + H₂O, what is one possible initial error?", "In balancing equations, what should be done last?", and "If you start with 2 moles of Na and react it with Cl₂, what is the balanced equation?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a standards aligned chemistry unit. The unit also covers Conservation of Atoms, Reading Equations as, Balancing Equations with Atom, Coefficients as Quantitative, Reaction Patterns from Evidence, and Products Using Reaction Types, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 9-12 chemistry classes, and for review at any point in the school year. This set is aligned to Virginia SOL standard CH.3c.
