An electrochemical cell is composed of pure copper and pure lead electrodes immersed in solutions of their respective divalent ions. for a 0.8 m concentration of cu2+, the lead electrode is oxidized yielding a cell potential of 0.500 v. calculate the concentration of pb2+ ions if the temperature is 25˚c. the standard potentials for cu and pb are +0.340 v and -0.126 v.

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
