How can Infrared Spectrometry and/or NMR spectroscopy be useful in helping to identify structural features of an adduct?
What volume of .100 M NaCl is needed to react completely with 5.00mL of .200 M Pb(NO3)2.
The decomposition of hydrogen peroxid is second order in H2O2. If 50 grams of 30% hydrogen peroxide is placed in a beaker within a sealed environment, what will be the concentration of hydrogen peroxide
The column is run with a solvent system based on hexanes, but which becomes more polar with the addition of more and more dichloromethane over time. Predict the elution order.
Draw a Lewis structure for SO2 in which all atoms obey the octet rule. Show formal charges. 2 Draw a Lewis structure for SO2 in which all atoms have a formal charge of zero. Explicitly showing the zero charges is optional.
