. What is the purpose of the Ba(NO3)2 ? 2. What percent of Agl remains unprecipitated when the first amount of AgCl starts to precipitate? 3. What effect would the presence of 1 M ammonia have on the above titration? Be specific in your answer. Indicate how you would experimentally evaluate the equilibrium constant for the silver-amine complex. 4. Explain why you do not need to know the half-cell potential for the reference electrode in order to calculate the Ksp for AgCl and AgI. 5. Compare the methods that you used to determine the endpoint

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
