Important limitation
AI can misread a symbol, charge, coefficient, value, unit, condition, or assumption and can produce incorrect equations, chemistry, calculations, or conclusions. Chemistry AI is a study aid—not an authoritative laboratory, hazardous-material, medical, grading, or safety service. Verify the original problem and every important result.
