Calculate the concentration of oxalate ion (c2o42–) in a 0.175 m solution of oxalic acid (c2h2o4). [for oxalic acid, ka1 = 6.5 ×
Darina [25.2K]

C2H2O4 C2HO4- + H+

0.175 - x x x + y

C2HO4- c2o42– + H+

x - y y x + y

K2 = (y) (x +y) / (x-y)

As, y << x

So, K2 = (y) (x) / (x)

K2 = y =6.1 × 10^–5

Hence, concentration of (c2o42–) 6.1 × 10^–5 M

How the fossil evidence helped you put the landmasses together (what was your process)
Otrada [13]

Explanation:

The idea behind using fossils to correlate two land masses was first put into limelight by a British geologist, Williams Smith.

According to the principle of fossil and fauna succession "fossils and fauna succeed one another in a define order".

This implies organisms evolve in predictable manner.

Since we know that certain types of organisms live within a period in time on the earth surface, we expect that such organisms would be fossilized in the geologic record and preserved.

  • Identify the fossil record in one part of the land mass. Log the rock types with the corresponding fossils in them.
  • On the other side, repeat the same process.
  • Look for unconformity surfaces where some part of the stratigraphic records might have been lost.
  • If the fossil records on one side corresponds with that on the other other side, it suggests that the land masses must have once been joined together.
  • The logic is that when the organism were on the same land mass, they thrived and lived together.
  • They became fossilized together till the lands separated.
