“Mass can neither be created not destroyed” is the Law of Conservation of Mass commonly attributed to Antoine Lavoisier. Lavoisier did considerable research in this area, including proving that in a closed system mass must remain constant, but it was Mikhail Lomonosov who first proposed and provided evidence for the idea in 1711.
It is this law which insists that we balance our chemical equations.
When you can balance five chemical equations that fulfil the following criteria your teacher will award you this badge. You may use fractions.
- all equations must require stoichiometric coefficients to be placed on both sides
- equations may not contain “.” nomenclature
