Consider the following equilibrium system: 3o2(g) 2o3(g); keq = 1 which equation compares the concentration of oxygen and ozone?

a. [o2]3 = [o3]2

b. [o2] = [o3]

c. [o2] = [o3]3/2

d. [o2]2 = [o3]3

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
