1 mol = 6.023x10^23 number of molecules (Avogadro's number)
1 : 6.023x10^23
X : 4.91x10^22
(6.023x10^23)X = 4.91x10^22
X = 4.91x10^22/6.023x10^23
X = 0.082 Moles
The answer is eight electrons.
Answer:
1. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.
2. On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.
3. Scientists can use gamma rays to determine the elements on other planets.
Explanation:
the explanation is above lol
Yes it is true. Of course it is right.
Answer:
Kw= = [H3O+][OH-] = [H+][OH-].
Explanation:
In chemistry, the term 'equilibrium'' is a period or time in which the rate at which the product is been produced or generated is equal to the quantity of the reactants reacting. In order way, we can say the equilibrium is when forward Reaction is equal to the backward Reactions.
The general equilibrium expression for the self-ionization of water is given below;
Kw = [H3O+][OH-] = [H+][OH-].
The kw is now equal to 1.001x10-14 at 25°C. Kw which is the equilibrium constant is also refer to as the dissociation constant of water.
