Description: Flash animation with 4 chemical reactions to balance (find the stoichiometric coefficients). Interactive test - Level 1. Easy for beginning.
hydrogen + dioxygen = water
H2 + O2 → H2O
nitrogen + hydrogen = ammonia
N2 + H2 → NH3
carbon + dioxygen = carbon dioxide
C + O2 → CO2
carbon + dioxygen = carbon monoxide
C + O2 → CO
Chemical reaction : process in which one or more substances, the reactants, are converted to one or more different substances, the products.
