The statement is supported by the data, is that the youngest rocks on the seafloor were at the mid-ocean ridge.
<h3>
What is the evidence regarding the age of the rocks?</h3>
The data collected by scientists regarding rock ages along a mid-ocean ridge seafloor with mid-ocean ridge showing age of rock increasing the further from the ridge.
From the data, they found that the youngest rocks on the seafloor were at the mid-ocean ridge and the rocks get older with distance from the ridge crest.
Thus, the statement is supported by the data, is that the youngest rocks on the seafloor were at the mid-ocean ridge.

The acid dissociation constant or Ka is a value used to measure the strength of a specific acid in solution. For a general dissociation of an acid solution,
HA = H+ + A-
we express Ka as follows:
Ka = [H+] [A-] / [HA]
Where the terms represents the concentrations of the acid and the ions. Assuming that the weak acid in the problem is HA, we first calculate for the concentration of H+ from the pH.
pH = - log [H+]
3.25 = - log [H+]
[H+] = 0.0005623 M
By the ICE table, we can calculate the equilibrium concentrations,
HA = H+ + A-
I 0.175 0 0
C -x +x +x
--------------------------------------------------
E .174438 0.0005623 0.0005623
Ka = (0.0005623) (0.0005623) / .174438
Ka = 1.81x10^-6
I would separate a mixture of marbles, corks, and nails by using a magnet to remove the nails. Put the marbles and cork in water. Remove the floating cork.
