Chemical Reactions and Balancing Equations Simulation
Science · Chemical Reactions · Grade 5, Middle School, and High School
About this simulation
Chemical reactions rearrange atoms without creating or destroying them. The balanced equation 2H₂ + O₂ → 2H₂O fixes the reacting ratio and reveals the limiting reactant. Students can change hydrogen molecules and oxygen molecules and compare what happens. Use it for chemistry inquiry with Grade 5, Middle School, and High School on a projector or student device.
Standards: NGSS MS-PS1-5
What students can explore
- Count atoms before and after a reaction
- Identify the limiting reactant from molecule ratios
- Observe how temperature changes collision rate but not the balanced ratio
Learning objectives
- 1Predict how changing hydrogen molecules will affect the water molecules formed, then test the prediction.
- 2Use evidence from the interactive visual to explain the result.
