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.

of oxygen at STP would be required to react completely with 38.8g of propane.
<u>Given that :</u>
molar mass of propane = 44 g/mol
mass of propane = 38.8 g
∴ Moles present in 38.8 g of propane =
= 0.88 mole
<u>applying rule of balanced equations </u>
1 mole of propane = 5 moles of oxygen
0.88 mole of propane = 5 * 0.88 = 4.4 moles of oxygen
Note : volume of 1 mole of oxygen at STP = 
∴Total volume of oxygen required at STP = 22.4 * 4.4 = 
Hence we can conclude that the volume of oxygen at STP required to react completely
