Lava that formed in these columns of Iceland is basaltic lava.
<h3>What is molten basaltic lava?</h3>
The Icelandic type causes the effusions of molten basaltic lava that flow from long, parallel fissures. Such outpourings produce lava plateaus. mountain type of mountains are formed due to such type of eruption of lava. The mountain was formed when the eruption occur under the ice sheet. Basaltic lava is another name of mafic lava. Mafic lava is molten rock that contain iron, magnesium and lower amount of silica. When mafic lava cools on the earth's surface, it produces basalt.
So we can conclude that Lava that formed in these columns of Iceland is basaltic lava.

Answer:

Explanation:
Hello,
In this case, since the acid is monoprotic, we can notice a 1:1 molar ratio between, therefore, for the titration at the equivalence point, we have:

Thus, solving for the moles of the acid, we obtain:

Then, by using the mass of the acid, we compute its molar mass:

Regards.
There are 1.456 moles of hydrogen in 5.2 moles of C7H18
