Chemical Reactions and Equations
Build the intuition first. Get the model right in your head before any number goes on paper.
Work through these
- Chemical equation balancerMove coefficients and watch every atom balance in real time.
- General reaction laboratoryChoose reviewed reactants and conditions, observe products, balance atoms, calculate stoichiometry and inspect the energy change.
- Redox and electrochemistryTrack the electrons and read the cell potential.
- Stoichiometry laboratoryMove from mass to moles, particles, limiting reagents, yield and formulas with every step visible.
