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:
Types Descriptions
Flows occur when soil or rock acts like a liquid
Slumps a slice of material that moves as one piece along a curved surface
Landslides made up of unconsolidated rock; includes rockslides and avalanches
Creeps material that moves slowly down gently sloping areas
Explanation:
Googled it.
H2O or water, all humans are mostly mad of water and water covers most of the earth
X4O10
Let molar mass of X be y
molar mass = 4y + 10 x 16 = 4y+160
so, moles = 85.2 / (4y+160)
Moles of oxygen = 10 x [85.2 / (4y+160) ]
Mass of oxygen = 16 x 10 x [85.2 / (4y+160) ]
which is 48.0
so, 48 = 16 x 10 x [85.2 / (4y+160) ]
Solve the equation to get y.
y = 31
