Chemical Reactions
Explore how substances change through chemical reactions, from balancing equations to predicting products. These quizzes focus on core reaction types, energy changes, and evidence of reactions, helping you connect symbols and formulas to real lab observations.
Quizzes
Balance equations with coefficients only
Sharpen your balancing skills by adding coefficients only—no changing subscripts. You’ll practice conserving atoms across reactants and products in common reaction types. With mixed difficulty, it’s a solid warm-up for class, labs, or exam prep.
Classify reactions: synthesis, decomposition, and more
Sort chemical equations into the right reaction type, from synthesis and decomposition to single and double replacement. You’ll get a mix of straightforward patterns and trickier cases where coefficients or states can distract you. Pick your question count and difficulty, then practice recognizing what’s really changing in the reaction.
Predict products for common reaction patterns
Sharpen your organic chemistry instincts by predicting products for common reaction patterns. You’ll identify major products, watch for regiochemistry and stereochemistry, and connect reagents to outcomes. Choose how many questions you want and set the difficulty to match your current level—then learn from each attempt.

What you’ll practice
These Chemical Reactions quizzes help you identify reactants and products, classify common reaction types, and work with balanced chemical equations.
You’ll also practice spotting evidence of reactions (gas, precipitate, color or temperature change) and linking reactions to conservation of mass.
How the quizzes work
Each question has 4 answer options, and there’s no timer, so you can focus on accuracy and reasoning rather than speed.
Quizzes vary in difficulty and length across the category, so you can start with fundamentals and move toward more multi-step problems as you improve.
- Balance chemical equations and apply conservation of atoms
- Classify reactions (synthesis, decomposition, single/double replacement, combustion)
- Predict products using patterns and basic reactivity rules
- Connect observations to reaction outcomes (precipitate, gas formation, heat)
- Interpret symbols, states of matter, and coefficients in equations
Quick facts about chemical reactions
Chemical reactions rearrange atoms by breaking and forming bonds, but the total number of each type of atom stays the same—this is why balancing equations matters.
Many everyday processes are reactions too, including rusting (oxidation), digestion (complex reaction pathways), and combustion in engines (rapid oxidation releasing energy).
