## Description

Understand chemical equations instead of simply memorizing them.

Chemical Equations Trainer guides you step by step from the fundamentals to advanced redox and ionic equations. Guided lessons, interactive exercises, clear explanations, and progressive hints help you understand chemical reactions and balance equations with confidence.

Guided learning content

Learn the essential concepts behind:

• Atoms and element symbols
• Coefficients and atom balances
• Reaction families
• Oxidation and reduction
• Redox reactions and half-reactions
• Oxidation numbers
• Ionic equations and spectator ions
• Net ionic equations

A reference table of common oxidation numbers is always available directly inside the app.

Interactive exercises

• Balance complete chemical equations
• Add one or more missing coefficients
• Count atoms and compare both sides
• Select the correctly balanced equation
• Find errors in chemical equations
• Identify reaction types
• Predict reaction products
• Build and enter equations yourself
• Convert word equations into chemical equations
• Identify spectator ions
• Create net ionic equations
• Determine oxidation and reduction
• Complete half-reactions
• Calculate oxidation numbers

The guided balancing trainer displays a live atom balance while you work. You can immediately see which elements are balanced and which still need adjustment.

Learn more effectively

• Easy, Medium, and Hard difficulty levels
• Mixed practice across different topics
• Immediate correct or incorrect feedback
• Complete solutions and explanations
• Step-by-step hints
• Automatic review of previous mistakes
