I *think* through weathering and erosion. Hope this helped
They are invisible to us ,but they little shining balls that come together.
<span>First you will need to know the conversion between atm and mm Hg. It is 1 atm = 760 mm Hg
Then you need to solve for the mm Hg
(0.550 atm) * (760 mm Hg/1 atm) = x mm Hg
x = 418 mm Hg</span>
Answer:
9 : 8
Explanation:
Aluminum oxide has the following formula Al₂O₃.
Next, we shall determine the mass of Al and O₂ in Al₂O₃. This can be obtained as follow:
Mass of Al in Al₂O₃ = 2 × 27 = 54 g
Mass of O₂ in Al₂O₃ = 3 × 16 = 48 g
Finally, we shall determine the mass ratio of Al and O₂. This can be obtained as follow:
Mass of Al = 54 g
Mass of O₂ = 48 g
Mass of Al : Mass of O₂ = 54 : 48
Mass of Al : Mass of O₂ = 54 / 48
Mass of Al : Mass of O₂ = 9 / 8
Mass of Al : Mass of O₂ = 9 : 8
Therefore, the mass ratio of Al and O₂ in Al₂O₃ is 9 : 8
