In a chemical reaction, 10 moles of the element aluminum react with 7.5 moles of oxygen gas. This produces 5 moles of aluminum oxide (Al2O3).

20Al + 15O2 → 10Al2O3
4Al + 3O2 → 2Al2O3
Al + O2 → Al2O3
10Al + 7.5O2 → 5Al2O3

D?10Al + 7.5O2 → 5Al2O3

What's the question? I assume you want to know the equation?
Balance the equations. C is not balanced. A, B, D are balanced BUT what is the one with the lowest coefficients?

Dude, all we want is the answer to the freakining equation
Answered by Late but helpful
It's B, the 4AI + 3O2 --->2A would be the lowest. If you would just explain and give the answer learning would be easier.
