The density of phosphorus vapor at 310 degrees celcius and 775 mmHg is 2.64g/L. what is the molecular formula of the phosphorus under these conditions?
An acid with a Ka of 1 x 10-8 is titrated with NaOH, both solutions being 0.020 M. What should the Ka of the indicator be, in order to obtain the best end point
Blood alcohol content (BAC) is often reported in weight-volume percent (w/v%). For example, a BAC of 0.08% corresponds to 0.08 g CH3CH2OH per 100 mL of blood. In Ontario, and the rest of Canada, the maximum legal BAC for fully licensed drivers is ..
Calculate the formula weight of CuSO4 . Use the following atomic weights: Cu is 63.5463 g/mol, S is 32.0666 g/mol, and O is 15.99943 g/mol. Your reported answer should have the correct number of significant figures and units.
If the reaction is allowed to proceed until all substances have reached their equilibrium concentrations, determine delta G for the reaction.
Consider the proposed mechanism for a reaction below. What is the rate law for the overall reaction?
Consider the equation A(aq) + 2B(aq) 3C(aq) + 2D(aq). In one experiment, 45.0 mL of 0.050 M A is mixed with 25.0 mL 0.100 M B. At equilibrium the concentration of C is 0.0410 M. Calculate K.
