Simulation of Law of Relative Formular mass

Relative formular — Simulation Description Relative Formula Mass Simulation — Description & Class Activity What the simulation does Students build molecules atom by atom by clicking element tiles on the left panel. Each atom appears as a coloured 3D sphere in the builder area. The balance scale tilts in real time as the molecule gets

Simulation of Law of conservation of mass

Law of Conservation of Mass — Simulation Description A conical flask sits on a digital lab balance. Inside the flask are marble chips (calcium carbonate, CaCO₃) in hydrochloric acid (HCl) — a classic GCSE reaction that produces carbon dioxide gas as a visible product. Students choose whether the flask is open or closed before starting.
