Zinc metal reacts with excess hydrochloric acid to produce hydrogen gas according to the following equation: Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)
The product gas, H2, is collected over water at a temperature of 20 degrees C and a pressure of 750 mm Hg. If the wet H2 gas formed occupies a volume of 9.18 L, the number of grams of H2 formed is g. The vapor pressure of water is 17.5mm Hg at 20 degrees C.

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 .
