Which half reaction is associated with the anode? Sn(s) —_— Sn2+ (aq) + 2e-
Sn2+ (aq) + 2e--> Sn(s)
Pb2+ (aq) + 2e-->Pb(s)
Pb(s)->Pb2(aq) + 2e-

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.

explanation:

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
