50.0mL of rhubarb juice are titrated with 0.1000 M NaOH and 34.8mL of this NaOH solution are needed for neutralization. Assuming the acidity of the juice is due to oxalic acid (a di-protic acid), H2C2O4 (90.04g/mol), find out the weight of oxalic acid (in grams) per liter of juice
Calculate kp given that the initial pressures of nitrogen are 95 atm and 80 atm, respectively, and the equilibrium pressure of nitrogen oxide is 6.0 atm. I know the answer is 5.1x10^-3. I am trying to find how is that number possible.
Does 1,3-cyclohexanediol contain any stereocenters. If so, mark them then determine how many different stereoisomers exist. Draw Fischer projections for all unique stereoisomers and identify the sets of enantiomers and diastereomers.
