PLEASE HELP An electrochemical cell has the same following standard cell notation. Mg(s) | Mg2 || Ag+(aw) | Ag(s)

What is the standard potential for the cell?

Is this a spontaneous of non spontaneous reaction? Explain your answer

Is this a galvanic cell or an electrolytic ce? explain your answer

Thank you!!

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

In which situation can a mixture always be called a solution

A50.0g sample of liquid water at 0.0 c ends up as ice at -20.0 c. how much energy is involved in this change?
