If 4 moles of aluminum react with 3 moles of oxygen, how many moles of aluminum oxide are formed?
2 moles
3 moles
4 moles
6 moles
The balanced equation is 4Al + 3O2 → 2Al2O3, which shows that 4 moles of Al produce 2 moles of Al2O3.

Q
Q: If 4 moles of aluminum react with 3 moles of oxygen, how many moles of aluminum oxide are formed?
Solution: The balanced equation is 4Al + 3O2 → 2Al2O3, which shows that 4 moles of Al produce 2 moles of Al2O3.
Steps: 4
Step 1: Write down the balanced chemical equation for the reaction between aluminum and oxygen. The equation is 4Al + 3O2 → 2Al2O3.
Step 2: Identify how many moles of aluminum (Al) are used in the reaction. In this case, it is 4 moles.
Step 3: Look at the balanced equation to see how many moles of aluminum oxide (Al2O3) are produced from 4 moles of aluminum. The equation shows that 4 moles of Al produce 2 moles of Al2O3.
Step 4: Conclude that if 4 moles of aluminum react, then 2 moles of aluminum oxide are formed.
