The answer would be D. The only minerals harder than corundum is diamond.
NO, it should not be the process is still the same . the only factors about it that should change is the experiment itself.:)
Answer:
The moon to the direct right of the Earth relative to the Sun
Explanation:
Answer: The partial pressure of Argon , Neon and krypton are 48 kPa , 24 kPa and 8 kPa respectively.
Explanation:
According to Raoult's Law , the partial pressure of each component in the solution is equal to the total pressure multiplied by its mole fraction. It is mathematically expressed as

where,
= partial pressure of component A
= mole fraction of A
= total pressure
mole fraction of Ar = 

mole fraction of Ne = 

mole fraction of Kr = 

C = 84.71%
H = 5.88%
O = 9.41%
<h3>Further explanation</h3>
Given
3-phenylphenol, C12H10O
Required
The mass percent
Solution
Ar C = 12 g/mol
Ar H = 1 g/mol
Ar O = 16 g/mol
MW C12H10O = 170 g/mol
The mass percent :
C = (12x12/170) x 100%
C = 84.71%
H = (10x1)/170) x 100%
H = 5.88%
O = (1 x 16)/170 x 100%
O = 9.41%
