Hello there! The correct answer is B) odor.
When you are wafting something, you're checking its smell in a careful way so you don't get harmed by potentially harmful chemicals. The odor of something is how it smells, or what smell it gives off, making this the correct choice. You can also eliminate A and D since the beginning of the question states that they are two clear liquids, so the color and texture won't differentiate one from the other. As well as this, it would not be C since it isn't smart to taste test chemicals in a lab, unless your teacher says it's okay.
I hope this helps and have a great day! :)
The mole ratio Aluminium to Aluminum Oxide is 2 : 1
<h3>Further explanation</h3>
Given
Reaction
2Al + Fe ----> Al2O3 +2Fe
Required
The mol ratio
Solution
If we look at the reaction above, there is an element missing from the reactant i.e oxygen, because the number of atoms and elements involved in the reaction should be the same between the reactants and products.
So the possible and balanced reactions are:
<em>2Al(s) + Fe₂O₃ (s) → Al₂O₃ (s)+ 2Fe (s) </em>
From this reaction the ratio of Al: Al₂O₃ can be determined, which is 2: 1
