A buffer consists of 0.11 M NaH2PO4 and 0.38 M Na2HPO4. Phosphoric acid is a triprotic acid (Ka1 = 7.2 x 10-3, K42 = 6.3 x 10-8, K13 = 4.2 x 10-13).
(a) Which K, value is most important to this buffer?
O
Kq1 is most important.
O
K 2 is most important.
O
K 3 is most important.
(b) What is the buffer pH?

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
