Answer:
C) diamond, glass, water, air
Explanation:
This is the correct order of speed of light from slowest to fastest is diamond, glass, water, air.
For this we have to know the refractive indices of these medium which is;
Diamond = 2.417
Glass = 1.517
Water = 1.333
Air = 1.0003
Refractive index is the measure of bending of light passing from one medium to another which is equal to the velocity of light c in empty space divided by its velocity v in given medium.
So that means refractive index of a medium is inversely proportional velocity of light in given medium.
That means medium having more refractive index velocity of light is low in that medium.
Diamond has highest then glass then water then air which is 2.417, 1.517, 1.333, 1.0003 respectively.
So the correct order of speed of light from slowest to fastest is diamond, glass, water, air.
Answer:
And that means fish must be able to survive down here. This is due to a special property of water: the elasticity of H2O. We know that when the temperature sinks below freezing, water first contracts and then expands as it begins to turn to ice. Ice, being lighter than water, floats.
Explanation:
The property of water that allows fish to survive in a lake that is frozen over is the fact that ice is less dense than liquid water.

For Hg :
2405 g mol / 200.59 g = 0.0012 mol
For O:
( 2.5000 - 2.405 ) g mol / 15.999 g = 0.006 mol
0.012 : 0.006 = 2 Hg
0.006 : 0.006 = 1 O
Answer:
The empirical formula is Hg 2 O.
