GCSE Chemistry - Conservation of Mass #26

Описание к видео GCSE Chemistry - Conservation of Mass #26

Whether we look at the mass, Mr or number of atoms, the mass is always conserved in chemical reactions. However, it may sometimes appear as if the mass changes if some of our reactants or products are gases. We can fix this problem though by doing our reactions in a sealed container.
