<h3>Al + O2 -> Al2O3</h3>
Balance it:
<h3>2Al + 3O2 -> 2Al2O3</h3><h3 />
So you need 2 Al and 3 O2 to make 2 Al2O3 (aluminum oxide).
I'm going to assume you have all the O2 you need.
Since 2 mols of Al is needed to make 2 mols of the product, it's a 1:1 ratio. You get as much aluminum oxide for as much aluminum you burn.
So 12.5 mols if there is not a lack of the O2.

The pH classification line (potential of hydrogen) starts at 0 and ends at 14. Solutions that have a pH below 7 (which is the neutral), have more acidic characteristics. Solutions, on the other hand, that have their hydrogen potential greater than 7, have basic aspects. A substance with pH 8, therefore, has a basic <span>characteristic.

Answer:
Mixtures can be separated using a variety of techniques.
Chromatography involves solvent separation on a solid medium.
Distillation takes advantage of differences in boiling points.
Evaporation removes a liquid from a solution to leave a solid material.
Filtration separates solids of different sizes.
Tundra soils are formed at high latitudes which leaves the tundra always very cold. Tundra soils are generally frozen, and are classifed as Gelisols (this means that permafrost are within 100 cm of the soil surface). These permafrost are as a result of the freezing by winter of the underground water that was accumulated in summer. These soils freeze and thaw alot and as result of that, moisture do not permeate the soil easily. Also, due to this harsh temperature and underground permafrost, most organisms that died in the tundra are preserved within the soil.
