Some donor centers have implemented the practice of diverting the first few milliliters of blood collected into a pouch attached to the collection bag.  What is the purpose of this procedure?

Platelet refractoriness necessitates the use of:

Which of the following transfusion reactions can be linked to the administration of whole blood to a patient with cardiac insufficiency?

Calculate the freezing point of a solution of 20.0 g methyl salicylate, C7H6O2, dissolved in 800. g of benzene, C6H6. Kf for benzene is and the freezing point is 5.50°C for benzene.

What factor affects the rate of a chemical reaction?

The following set of data was obtained by the method of initial rates for the reaction:BrO3-(aq) + 5 Br-(aq) + 6 H+(aq) → 3 Br2(aq) + 3 H2O(l).What is the rate law for the reaction?

For the hypothetical second order reaction: A → products, the general rate law is: rate = k2. How long is the third half-life of the reaction if 0 is 0.080 M and the first half-life is 22 minutes?

What is the molality of ethanol in a solution made by dissolving 14.6 g of ethanol, C2H5OH, in 53.6 g of water?

If the units for rate are M s-1, what are the units for the rate constant, k, if the overall order of the reaction is three?

The isomerization reaction, CH3NC → CH3CN, is first order and the rate constant is equal to 0.46 s-1 at 600 K. What is the concentration of CH3NC after 0.20 minutes if the initial concentration is 0.10 M?
