The decomposition of hydrogen peroxide is given by this equation: 2h2o2(l) ? 2h2o(l) o2(
g. calculate the mass of water (in grams) and the volume of oxygen at stp formed when 2.00x10-3 mol of hydrogen peroxide is decomposed.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
