Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes
hope this will help
Something that does not have the ability to react is considered inert. <span> In chemistry, the term </span>inert<span> is used to describe a substance that is not </span>chemically<span> reactive. Hope this answers the question. Have a nice day.</span>
Answer: 
Explanation:
Solubility product is defined as the equilibrium constant in which a solid ionic compound is dissolved to produce its ions in solution. It is represented as
The equation for the ionization of the 
is given as:
When the solubility of is S moles/liter, then the solubility of 
will be S moles/liter and solubility of 
will be 2S moles/liter.
By stoichiometry of the reaction:
1 mole of gives 1 mole of 
and 2 moles of
