I think Thermodynamics is the aspect of a substance that contributes to a high or a low entropy. Entropy is the measure of chaos or disorder in a closed system. Entropy can be changed by a number of factors, for example, changing to a higher temperature increase entropy, change of states from solid to liquid and from liquid to gas causes changes in entropy, more bonds in a substance increases entropy, among other factors.
Answer:
Mass = 182.4 g
Explanation:
Given data:
Number of moles of Al₂O₃ = 3.80 mol
Mass of oxygen required = ?
Solution:
Chemical equation:
4Al + 3O₂ → 2Al₂O₃
Now we will compare the moles of aluminum oxide and oxygen.
Al₂O₃ : O₂
2 : 3
3.80 : 3/2×3.80 = 5.7
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 5.7 mol × 32 g/mol
Mass = 182.4 g
