Answer: Option (D) is the correct answer.
Explanation:
When aluminium reacts with oxygen, it results in the formation of a layer of aluminium oxide on its surface.
This outer layer gets corroded but it forms a protective coating for the inner layers that prevents from further corrosion.
Thus, we can conclude that metals like aluminum can react with oxygen to form coatings that prevent corrosion.

Answer:
Mass of benzene is: 149.3 g
Explanation:
Let's use density to calculate mass.
Density = Mass / Volume
Mass = Density . volume
Be careful, because density is in g/mL and the volume is in L. So let's convert the L to mL: 0.170 L . 1000 mL / 1L = 170 mL
0.8787 g/mL . 170 mL = Mass of benzene
Mass of benzene is: 149.3 g
Answer:
Degrees Kelvin = Degrees Celsius + 273.15
Degrees Kelvin = -13 + 273.15
= 260.15
