the solubility of a gas in water at 25 degree C is .022 mol/L. What is the Henry's law constant for the gas if the partial pressure of the gas in air is .0088 atm?
Compounds containing carbon-carbon triple bond undergo the Diels-Alder reaction. Formulate the product formed by the reaction of
calculate (a)molality? (b)molarity of NaCl? (c) What is the mass/mass and remove the most loosely held e- from a gaseous atom in a ground state
calculate the mass loss on heating 1.200 g of a NaHCO3-NaCl mixture containing 65% NaCl
Uric acid dissociates as shown in the figure at the right with a pKa of 5.80, and can be treated as a simple monoprotic acid in this pH range. Its solubility in urine depends on the relative amount of protonated and unprotonated forms. A urine sam..
