Will a precipitate form when a solution of sodium acetate and a solution of ammonium sulfate mix and what is the net ionic equation that describes the chemical change. what about for a solution of calcium chloride and a solution of mercury (I) nitrate
Provide some diagnostically useful differences you would expect in the IR spectra between starting materials and product for the reaction you carried out (e.g. if I was asked this regarding the oxidation of cyclohexanol to cyclohexanone
How many grams of NaN3 are required to produce 340 L of nitrogen gas if the gas has a density of 1.25 g/L?
Unknown Q is determined to have a molecular formula of C6H12O. Q is not optically active, and passing it through a chiral column does not separate it into enantiomers.
Describe the pH of a buffer solution consisting of 100 mL containing 0.1M CH3COOH and 0.125M CH3COO- , both before and after addition of 10 mL of 0.25M HCl. Ka = 1.8 x 10-5.
Your friend decides to decrease cooking time for spaghetti noodles by adding table salt to 2.0 L water. How much table salt (NaCl) must be added to the water in order to raise the boiling point by 4.0?C? (Kf = 1.86?C/m, Kb = 0.512?C/m)
You are given solutions of HCl and NaOH and must determine their concentrations. You use 27.8 mL of NaOH to titrate 100. mL of HCl and 22.8 mL of NaOH to titrate 50.0 mL of 0.0790 M H2SO4.
