Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind
Alpha particle consists of 2 protons and 2 neutrons while beta particle consists of electrons. So one time of alpha emission. the result nuclide is Pb-214.
E. decomposition
hope this helps!
The formula for pH given the pKa and the concentrations
are:
pH = pKa + log [a–]/[ha]
<span>
Therefore calculating:</span>
3.75 = 3.75 + log [a–]/[ha]
log [a–]/[ha] = 0
[a–]/[ha] = 10^0
<span>[a–]/[ha] = 1</span>
11.9 if i read your question correctly sorry if it’s wrong lol
