Explain the mechanism of toxicity ( phase I and phase II products and metabolites ) for exposure to NAPHTHALENE and vinyl acetate.
Show that the Slater determinant formalism automatically incorporates the Pauli exclusion principle by evaluating the He ground-state wave function of Equation 10.8, giving both electrons the same quantum numbers.
What is the white precipitate that forms while the reaction mixture is heated. The reaction is the hydrolysis of the ester Butyl benzoate yields products 1-butanol and benzoic acid.
To determine its identity, 0.150g of the unknown was dissolved using 10.00ml, 0.531 M HCl. Three drops of methyl orange was added to the solution and then titrated with 0.2440 M NaOH.
Suppose that the atomic mass unit (amu) had been defined as one-twelfth of the average mass of an atom of nitrogen instead of one-twelfth of the mass of an atom of carbon-12. What would the average atomic mass of potassium be on this new scale
Calculate the final temperature of 32 mL of ethanol initially at 11 degrees C upon absorption of 562 J of heat.
The pH of human muscle fluids is 6.8. Calculate the value of H3O+ in muscle fluid at 25 degrees Celcius. The answer should be in scientific notation.
What is the molarity of a NaOH solution if 28.2 mL of a 0.112 M H2SO4 solution is required to neutralize a 25.0-mL sample of the NaOH solution?
If a solution contains 0.01 M Ca^2+, 0.01 M Zn^2+, and 0.01M Ni^2+ ions and you want to separate them using aqueous (NH4)2C2O2, which ion will precipitate first as an oxalate, CaC2O4, ZnC2O4, or NiC2O4
An emission line from K atoms is found to have two closely spaced components, one at 766.70nm and the other at 770.11nm. Account for this observation, and deduce
Three resonance structures of the following cation are possible. One resonance form is given below, but it is incomplete. Complete the given structure by adding non-bonding electrons and formal charges where necessary
A solution of 75.0g of benzene and 75.0g of toluene has a total vapor pressure of 80.9mmHg at 303K . Another solution of 100.0g benzene and 50.0g toluene has a total vapor pressure of 93.9mmHg at this temperature.
