Chemistry Lab Simulator

Receive a virtual sample, then select the glassware, reagents and order of steps before anything is mixed. The system calculates each reaction and reproduces what a wrong move causes: a temperature spike, a diluted solution, a stalled yield. Temperature, concentration and timing are set by hand, so every run differs. An AI review points to the exact stage where the method was broken and explains why. Learning mode adds step by step explanations. Exam mode removes every hint and leaves only the result. Laboratory procedure, rehearsed without spending a single reagent.
