Help your students build real understanding of chemical reactions through ninety questions that move from basic recognition to genuine reasoning about chemistry concepts.
Sample questions include "In a chemical equation, what do the coefficients represent?", "What is the balanced equation for the combustion of propane (C₃H₈)?", and "What is the primary purpose of a chemical 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 complete NGSS aligned chemistry unit. The unit also covers Types of Chemical Reactions, Balancing Equations, Identifying Chemical Reactions, Predicting Products, Chemical and Physical Change, and Reaction Energy Changes, 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 NGSS aligned review at any point in the school year. This set is aligned to NGSS standard HS-PS1-2.
