Answer: The value of for the half-cell reaction is 0.222 V.
Explanation:
Equation for solubility equilibrium is as follows.
Its solubility product will be as follows.
Cell reaction for this equation is as follows.
Reduction half-reaction: ,
Oxidation half-reaction: , = ?
Cell reaction:
So, for this cell reaction the number of moles of electrons transferred are n = 1.
Solubility product,
=
Therefore, according to the Nernst equation
At equilibrium, = 0.00 V
Putting the given values into the above formula as follows.
=
= 0.577 V
Hence, we will calculate the standard cell potential as follows.
= 0.222 V
Thus, we can conclude that value of for the half-cell reaction is 0.222 V.
Avogadro's number; it describes the number of representative particles in one mole of a substance. Avogadro's number is. 6.022×10^23mol
The answer is d. isotopes. The same element must have the same protons. And the atoms with same protons and different neutrons are called isotopes.
Some examples of physical properties are:
color (intensive)
density (intensive)
volume (extensive)
mass (extensive)
boiling point (intensive): the temperature at which a substance boils.
melting point (intensive): the temperature at which a substance melts.
Answer:
The first element is always named first, using entire element name.
Second element is named using its root and adding the suffix -ide.
Prefixes are used to indicate the number of atoms of each element that are present in the compound.
