Oksi-84 [34.3K]

Answer:

boundary interactions: areas where plates move away from each other forming mid-ocean ridges or rift valleys.

divergent boundaries: this happens when 2 tectonic plates move away from each other. along these boundaries earthquakes and magma are common as they are rise from the mantle to the sruface making new oceanic crust.

convergent boundaries: this is an area on earth where 2 or more lithospheric plates collide. they will slide under one another creating a subduction.

transform boundaries:  transform boundary is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.

Explanation:

lithosperic means the solid outer part of the earth.

hope this helps and good luck!  :) <3

A sample of Al2O3 decomposed to pure aluminum and oxygen. After decomposition, 29.0 moles of Al were recovered. How many moles o
Rina8888 [55]

The decomposition of Al2O3 to form pure aluminum (Al) along with the release of oxygen (O2) gas can be represented by the following chemical reaction:

2Al2O3 → 4Al + 3O2

Based on the reaction stoichiometry:

2 moles of aluminum oxide decomposes to form 4 moles of pure aluminum

Therefore, if 29.0 moles of aluminum is recovered, then the moles of aluminum oxide required will be:

= 29.0 moles Al * 2 moles Al2O3/4 moles Al

= 14.5 moles of Al2O3
