Answer:
0.24V
Explanation:
First we must obtain the ionic strength of the solution I as shown in the image attached. This ionic strength can now be used to obtain the activity coefficient of the ions in solution by substitution of the value of the ionic strength obtained previously and the charge of the ion (Cu2+) into the equation for activity coefficient.
The activity of an ion is defined as the product of its activity coefficient and its concentration. This activity of copper II ion is now substituted into the Nernst equation to obtain the equilibrium potential required in the question.

Answer:
the physical and chemical properties of the products are different from the reactants
Explanation:
A chemical reaction involves the chemical combination of two or more elements/compounds called Reactants to give one or more different elements/compounds called Products. A chemical reaction occurs in such a way that the atoms of the reactants are restructured to form product(s) that is/are entirely different from the reactants.
In a chemical reaction, the physical and chemical properties of the products differ from that of the reactants since different chemical compounds/elements are formed as products. The physical properties of a substance, which include colour, melting and boiling point etc. will differ in the reactants and products formed. Also, the chemical structure and identity of the reactants will be changed to give rise to a different chemical property in the products.
