Which of the folio rock formation processes in NOT matched correctly? A) Melting & cooling = Ingenious rock formation
B) Heat & pressure = metamorphic rock formation
C) Magma cooling = metamorphic rock formation
D) sediments being deposited, compacted & cemented together = sedimentary rock formation
E) Weathering, erosion, deposition, compaction & cementation = sedimentary rock formation

I got e but you might want to wait for someone else to answer it just incase...

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
