This resource turns stoichiometry to predict outcomes into a complete, ready to use review for Grade 9-12 chemistry, covering the same idea from three different angles.
Students will answer questions such as "In the reaction 2 H₂ + O₂ → 2 H₂O, how many moles of water are produced from 4 moles of hydrogen?", "From the reaction N₂ + 3 H₂ → 2 NH₃, how many moles of NH₃ can be produced from 6 moles of H₂?", and "When 0.5 moles of NaOH react with excess HCl, how many moles of NaCl are produced?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
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, Stoichiometric Ratios, and Reaction Quantity Calculations, 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.
