The chemical structure of the acid form of acetylsalicylic acid is shown below with its speciation plot. the dashed line shows the conjugate base form. acetylsalicylic acid (aspirin) the ph in the stomach is about 1, and in the intestine it is about 5. select the correct statement below: (a) the drug is absorbed from the intestine because it is in a neutral fat-soluble acidic form. (b) the drug is absorbed from the stomach because it is in a neutral fat-soluble acidic form. (c) the drug is absorbed from the intestine and the stomach because it is in a neutral fat-soluble form in both. (d) the drug is absorbed from the intestine because it is in a neutral fat-soluble basic form. (e) the drug is absorbed from the stomach because it is in a neutral fat-soluble basic form.

The conventional equilibrium constant expression (kc) for the system below is: 2icl(s) ⇄ i2(s) + cl2(g) [cl2] ([i2] + [cl2])/2[icl] [i2][cl2]/[icl]2 none of the listed answers are correct [i2][cl2]/2[icl]

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap

Skills of homo sapiens were found an excavation. the skulls were preserved because the bodies were frozen. so, these fossils are (blank) fossils.the image shows the evolution of skulls beginning 2 to 3 million years ago. based on the image, modern human skulls(blank) ape skulls.
