Observable changes
Observable changes as per reaction type — gas evolution, precipitate, color change, or temperature change.
Particle interpretation
Particle view: atoms rearrange, bonds break and form, conserving atoms and charge.
Stoichiometry
Stoichiometric ratios from balanced coefficients.
Safety
Do not attempt hazardous preparations without training. Consult SDS and local safety rules.
