A spectrophotometric method for the quantitative determination of the concentration of Pb2+ in blood levels yields and Ssample of 0.19 for a 1.0 mL sample of blood that has been diluted to 5.0 mL. A second 1.0 mL sample is spiked with 2.0 microliters of a 1000 ppb Pb2+ standard and diluted to 5.0 mL, yielding an Sspike of 0.4. Determine the concentration of Pb2+ in the original sample of blood.
How does the collision theory account for the dependence of rate on the concentrations of the reactants?
Reaction of AsCl3 with Cl2 at low temperature yields a product, believed to be AsCl5, which shows Raman bands at 437,369, 295, 220,213, and 3cm-1. Detailed analysis of the 369 and 295 cm-1 bands show them to arise from totally symmetric modes.
Draw the basic repeating unit of polyethylene terephthalate (PET). Classify PET as a polyamide or polyester. Is PET a condensation or addition polymer? Explain.
Calculate the final hydrogen ion concentration of a solution after 25.0 mL of 0.500 M HCl is treated with 40.0 mL of 0.0500 M Ba(OH)2(aq) and diluted to 100.0 mL.

Write an overall balanced equation and a net ionic equation for the complete neutralization of aqueous H2SO4 with aqueous NaOH. Be sure to include phase designations such as (s) and (aq).
tripling the concentration of A increases the rate by a factor of 27, doubling the concentration of B has no effect on the rate, and tripling the concentration of C increases the rate by a factor of 3. Write down the rate law for this reaction.
If the test of such a breath sample yields a reading of 0.08%, what are the partial pressure and mole fraction of CH3CH2OH in the breath of the person who was tested? Assume the atmospheric pressure and temperature are 101 kPa and 21.0 oC, respect..
