50 points! A slurry of barium sulfate is ingested just before an X-ray of the gastrointestinal tract is taken because the precipitate is opaque to x-rays and thus defines the contours of the tract. The Ba- ion is toxic, but the compound is nearly insoluble. If 4Gº at 37°C (body temperature) is 59.1 kJ/mol for the process

BaSO4(s) = Ba²+(aq) + SO4²- (ag)

what is [Ba²+] in mol/L in the intestinal tract? Assume the only source of sulfate ions is the ingested slurry.

Which of these best describes the scientific process

What is the molecular formula for a compound that is 46.16% carbon, 5.16% hydrogen, and 48.68% fluorine? the molar mass of the compound is 156.12 g/mol

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
