Help your students build real understanding of chemical equations as models of change through ninety questions that move from basic recognition to genuine reasoning about how science works.

The set includes questions like "What is the role of a catalyst in a chemical reaction?", "When writing a chemical equation, what does (s) stand for?", and "When balancing a chemical equation, what should you never change?"
