Help your students build real understanding of stoichiometric ratios through ninety questions that move from basic recognition to genuine reasoning about chemistry concepts.
Students will answer questions such as "For the reaction 2Al + 3Cl₂ -> 2AlCl₃, what is the ratio of Cl₂ to AlCl₃?", "From the reaction 3H₂ + N₂ -> 2NH₃, what is the mole ratio of hydrogen to ammonia?", and "In the equation 2KClO₃ -> 2KCl + 3O₂, what is the ratio of KClO₃ to KCl?"
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 The Mole as a Counting Unit, Connecting Particles and Moles, Connecting Mass and Moles, Molar Reasoning in Quantitative, Reaction Quantity Calculations, and Composition Quantity Reasoning, 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.4b.
