Are suds formed?Are insoluble materials or precipitates formed?
what volume will it occupy? Assume constant pressure. Note the temperatures are given in two different units. Be sure to change each to deg K first.
Determine the free energy change associated with the above reaction (you might find it easier to first consider the movement of the two components of the system separately)
If the BaSO4 residue was baked in an oven at 100C for several hours rather than air drying, what effect would this have on its mass and how would the initial concentration of H2SO4 be affected
A pressure measuring device indicates that the blood pressure of a normal person oscillates between 120 mm Hg (at the peak of the heartbeat) and 80 mm Hg (between heartbeats).
