A buffer is made with 0.493 M of the weak base methylamine () with 0.493 M (KA = 5.6 x 10^-4) What is the pH of this buffer system?

If 0.100 M HBr is added to the buffer, what is the pH?

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

b. is the answer hoped i        

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
