A 3.00L container is rated to hold gas at a pressure no greater than 100atm. Assuming the gas law behaves ideally, what is the maximum number of moles a gas that this vessel can hold at 27 degrees C?
which mixture would not be expected to be homogeneous. pentanol and hexane, KBr and water, acetic acid and methanol, ethylene glycol and water, octane and heptane
By looking at the structure of tetrabutylammonium bromide, explain how this reagent can carry ions from the aqueous phase into the organic phase.
During the Purification of Lactate Dehydrogenase (LDH) experiment, you will need 50ml of buffer A150. Buffer A150 is 30mM Tris (pH 8.8) and 150mM NaCl. Given 1L of 1.5M Tris and 500ml of 5M NaCl,
