Try 3 free problems on balancing, classifying, and interpreting reactions. Want more reps? Premium opens the full 174-problem bank in sets of 3, 9, or 18.
Work these 3 to find out whether the reaction patterns are starting to click — or whether balancing and classifying still need more deliberate practice.
#4Balancing
Balance: _Al + _O2 → _Al2O3. What is the coefficient in front of O2?
#5Reaction Types
Which type of reaction is represented by: AB → A + B?
#6Net Ionic Equation
When AgNO3(aq) and NaCl(aq) are mixed, a white precipitate forms. Which net ionic equation is correct?
Prep for the test — not just the homework
The 3 free problems show you where you stand. The full bank is how you close the gaps before the test.
Randomized every time — fresh problems that force real understanding, not answer memorization
Full worked solutions — see exactly where your setup went off track, not just whether you were right
174 problems across balancing equations, reaction types, and predicting products
Quick (3), Standard (9), or Extended (18) — use whatever fits your schedule
Filter by type — focus on calculation, concept, or multi-step problems first
Filter by difficulty — dial in easy, medium, or hard problems as you build up
