Give your chemistry students a focused look at conservation of atoms with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
The set includes questions like "In a reaction where 2H₂ + O₂ → 2H₂O, how many hydrogen atoms are present in the products?", "How does balancing a chemical equation demonstrate conservation of atoms?", and "How many total atoms are present in the balanced equation 2H₂ + O₂ → 2H₂O?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a standards aligned chemistry unit. The unit also covers Reading Equations as, Balancing Equations with Atom, Coefficients as Quantitative, Reaction Patterns from Evidence, Products Using Reaction Types, and Classifying Reactions, 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.
