By absorbing hcl (g) in water, an 8 mol/l hydrochloric acid solution [sg = 1.12, cp = 2.76 j/(g solution °c) is produced. liquid water enters the absorber at 25°c and gaseous hcl is fed at 20°c and 790 torr (absolute) pressure. assume that all the hcl fed to the absorber is absorbed by water. take 1 l of product solution as the basis for your calculation. a) estimate the volume (in l) of hcl that must be fed to the absorber. (7 points) b) estimate the heat (in kj) that must be transferred from the absorber, if the product solution has a temperature of 40°c. (13 points) c) estimate the final solution temperature, if the absorber operates adiabatically.

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
