Question

How many moles of Al2O3 are needed to produce 95.4 moles of O₂ according to thefollowing balanced chemical equation: 2 Al2O3 -> 4 Al + 30₂?3.0014328647.763.6

Answer 1

Step-by-step explanation:

First, let's write the chemical equation:

`2Al_2O_3\rightarrow4Al+3O_2.`

We want to know how many moles of Al2O3 we require to produce 95.4 moles of O2. You can note that in the chemical equation we have 2 moles of Al2O3 reacted that produces 3 moles of O2, so we can state a rule of three, like this:
