Answer:
2.45×10^54
Explanation:
Mg(s) + Zn2+(aq) = Mg2+(aq) + Zn(s)
From the equation;
n= 2 moles of electrons
E°anode= -2.37 V
E°cathode= -0.76 V
From E°Cell= E°cathode - E°anode
E°Cell= -0.76-(-2.37) = 1.61 V
Recall that E°cell= 0.0592/n log K
1.61= 0.0592/2 log K
log K = 1.61/0.0296
K= Antilog (54.39)
K= 2.45×10^54
Answer:
<u>The atoms move more </u><u>quickly</u><u> and closer together</u>.
Your answer would be C. Alpha decay involves the ejection of 2 protons and 2 neutrons from the nucleus for a total of 4 amu lost. This form of decay is most common in heavy elements.
