Question

What is the reduced ratio value for aluminum to oxygen

(Al : O2) for student 2
A. 0.56 : 1
B. 1.8 : 1
C. 7.0 : 1
D. 2.0 : 1

Answer 1

To find the reduced ratio value for aluminum (Al) to oxygen (O2), you need to determine the simplest whole-number ratio of moles of aluminum to moles of oxygen in the compound.

The molecular formula for aluminum oxide (a common compound of aluminum and oxygen) is Al2O3. This means that for every 2 moles of aluminum, you have 3 moles of oxygen.

So, the reduced ratio value for aluminum (Al) to oxygen (O2) is 2 : 3.

None of the options provided match this ratio exactly. If you had to choose the closest option, it would be:

B. 1.8 : 1

But please note that this is not the exact ratio, as the exact ratio is 2 : 3.
