Waves produced a diffraction pattern.
Results supported the wave theory of light.
Answer:
Ethanol is soluble in water because it has a hydroxyl group which allows it to form hydrogen bonds with the water molecules. This is why hexanol is not soluble in water.
Al atom has 13 protons, 13 electrons.
Mass number = number protons + number neutrons
27 = 13 + number neutrons,
number neutrons =27 - 13 = 14 neutrons .
Ion Al³⁺, lost 3 electrons.
So, in Al³⁺, 13-3=10 electrons.
So, ion Al³⁺ has 13 protons,14 neutrons, 10 electrons.
6.02 times 10 to the 23rd power
