Answer:
The diameter of the oil molecule is 
.
Explanation:
Mass of the oil drop = 
Density of the oil drop = 
Volume of the oil drop: v
Thickness of the oil drop is 1 molecule thick.So, let the thickness of the drop or diameter of the molecule be x.
Radius of the oil drop on the water surface,r = 41.8 cm = 0.418 m
1 cm = 0.01 m
Surface of the sphere is given as: a = 
Volume of the oil drop = v = Area × thickness
The thickness of the oil drop is and so is the diameter of the molecule.
Answer:
This is a single replacement reaction because I replaces Br.
Answer:
From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.
Explanation:
Analyzing a biomolecule X, a scientist verifies that it is made up of Carbon, Hydrogen, Oxygen and Nitrogen, in addition to releasing water when it joins with other similar molecules to form polymers. Considering these antecedents, it can be inferred that biomolecule X corresponds to: A Steroids B fatty acid C nucleotide D amino acid E monosaccharide (for people who dont speak spanish)
ok you answer is probably A
if wrong C maybe
~hope~
The correct answer is oceanic crust, 80 km, Hope this helps let me know.
