How many moles of AgNO3 must react to form 0. 854 mol Ag? mol AgNO3.
babunello [35]

The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.

The balanced chemical equation for the dissolution of silver nitrate has been:

\rm AgNO_3\;\rightarrow\;Ag^+\;+\;NO_3^-

The aqueous solution of silver nitrate has been dissociated into the constituent silver and nitrate ions.

In a balanced chemical equation, the coefficient has been equivalent to the moles of each reactant forming the moles of product.

From, the balanced equation,

\rm 1\;mol\;AgNO_3=1\;mol\;Ag

The given moles of Silver has been 0.854 mol. Thus, the moles of silver nitrate required has been given as:

\rm 1\;mol\;Ag^+=1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;\times\;1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;mol\;AgNO_3

The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.

Are two atoms of same element identical​
goldenfox [79]

Answer:

No. Two atoms of the same chemical element are typically not identical. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.
