If 85 g of NH4Cl reacts with 130 g of CA(OH)2 according to the following reaction, what is the maximum mass of ammonia that can be formed?

2NH4Cl + Ca(OH)2> CaCl2 + 2NH3 + 2H2O

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 .
