I hope this helps :)
Answer:
20 protons and 20 electrons
Explanation:
Answer:
stratosphere - The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward.
mesosphere - The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere
thermosphere - The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere.
The standard cell potential is obtained from the equation of the reaction.
<h3>What is the standard cell potential?</h3>
The standard cell potential is obtained from the equation of the reaction. Now we have the overall cell equation as from the half reactions as;
Oxidation half reaction;
Al(s) --->Al³+ (aq) + 3 e
Reduction half equation;
Cu²+ (aq) + 2 e →→ Cu(s)
Standard cell potential Eºcell = 0.34V - (-1.66 V) = 2 V
Now;
ΔG = -nFEcell
ΔG = -(2 * 6 * 96500 * 2)
ΔG = -2316kJ
E = 2 - 0.0592/6 log [0.0025]/[3.5 M]
E = 2 + 0.031
E = 2.031 V
