Which activity is most likely involved with the study of electrochemistry?
combining acetic acid with zinc metal
adding sodium hydroxide to sulfuric acid
placing zinc and copper in an electrolyte
mixing sugar crystals and water in a beaker

The answer is that, from the answer choices, placing zinc and copper in an electrolyte is most likely involved with the study of electrochemistry.

Electrochemistry is the use study of the chemical reactions in relation to electric energy. It comprises the use of electric energy to produce chemical changes and the use of chemical reactions to produce electric energy.

The chemical reactions that produce or use electric energy are carried out in electrolytic cells.

Electrolytic cells consist of a pair of electrodes submerged in an electrolytic solution.

Zinc and copper are good pieces of conductors that work as electrodes in the electrolytic solution. Then, this is the correct answer..    

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.

The correct answer is b) false
