Calculate the percent ionization of 0.085 moles/l of lactic acid in a solution containing 0.050 moles/l sodium lactate
The reaction that you will conduct in this experiment is known as a "haloform" reaction. When a methyl ketone is used as a substrate, what is it converted to in this reaction?
If 3.420g of ^226 Ra (t 1/2= 1620 yrs) is separated from its decay products and placed in a sealed 1L vessel, what is the partial pressure (in torr) of helium after 45 days if the vessel is at 0 degrees C? The half life of Rn is = 3.82 days
atomic radius for Copper ,and assuming the atoms to be rigid spheres,
7.50 mL of 0.125 M HCl is added to the 100.0 mL of the buffer solution. Calculate the new [NH3] and [NH4Cl] for the buffer solution. Calculate the new pH of the solution.
