Recently a Mr. A. U. Ag was suspected of poisoning their rich relative, Auntie G. Richey with D-Con. The patient eventually was treated with Vitamin K1 antidote. The rate constant for eliminating the poison from her system was 8.75 x 10-4 hr -1 at 37 o C. The initial level of poisoning is 170 micrograms per liter of blood. The molar mass for the hydrophobic poison is 308.33 grams per mole. a. What is the order of the elimination process? Explain in 1-2 sentence. b. What is the general rate law expression for this process? c. Calculate the half-life for elimination of the poison from the body. d. Calculate the total time that the deliberate Vitamin K1 treatment is required to reach a safe level, 10 micrograms per liter blood.
If a solution containing 30.87 g of mercury(II) chlorate is allowed to react completely with a solution containing 5.102 g of sodium sulfide,
Calculate the pH of a buffer solution that is 0.250 M in HCN and 0.170 M in KCN. For HCN, Ka = 4.9 x 10^-10 (pka = 9.31). Use the equilibirum approach to calculate this pH
A piece of iron with a mass of 350g at 300 C is added to 1.00kg of water at 20 C. what is the final temperature of the iron
How can you calculate the quantitative precipitation of barium in a solid mixture of sodium chloride and barium chloride
After precipitation is complete, the concentration of the OH- is -0.10M and the measured cell potential is 1.05V. Calculate the Ksp value for Zn(OH)2(s). Zn(OH)2 > Zn^(2+)(aq) + 2OH-(aq) Ksp = ? PLEASE show ALL work, I rate ALL 5 stars.
No desiccator is available. The sodium carbonate is cooled to room temperature, but the humidity in the room is high. how will this affect the reported molar concentration of the hydrochloric acid

A solution of NaCl dissolved in water will have 1) a lower freezing point than pure water 2) a lower boiling point than pure water 3) larger crystals when frozen than pure water 4) a lower density than pure water 5) a higher freezing point than pu..
the effect of epinephrine binding to B-receptors is well known. epinephrine also binds to alpha-receptors. which of the following would NOT result following the binding of epinephrine to alpha-receptors in the liver
the temperature of the calorimeter (including its contents) rose from 23.18oC to 27.65oC. What mass, in g, of benzoic acid was burned. here is what i did, 3226/122.13=26.41 delta t =4.474 so 4.474*12.5/26.41 =2.12 is the answer 2.12g
