<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 dinosaur dies and is washed away in a flood. The body is buried in sediment (mud or sand) and eventually the body is covered. ... Eventually, the fossil skeleton comes to the surface and is discovered.
<h3><u>Answer</u>;</h3>
B) Al2O3
<h3><u>Explanation;</u></h3>
Aluminium reacts with oxygen to form aluminium oxide.
The chemical reaction for the reaction between Aluminium and Oxygen is;
4Al+ 3O₂→ 2Al₂O₃
Therefore;
Compound X is Aluminium oxide (Al₂O₃)
