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.
Because they’re both made up of two substances that are not chemically combined
The atomic number of an element tells you how many protons each atom has. Losing an electron won't affect the number of protons. It will, however, change the charge on the atom. Protons are positive and electrons are negative. If there's more positive than negative then the atom has a positive charge. So the charge for the sodium atom would be +1
Answer:
The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance(mol) .
