Answer:
B) neuron or nerve cell work is to carry messages
Answer:
double replacement
Explanation:
The reaction equation is given as:
Pb(NO₃)₂ + 2KI → PbI₂ + KNO₃
This reaction is a double displacement reaction.
In this form of reaction, there is an actual exchange of partners to form new compounds.
AB + CD → AD + CD
One of the following condition serves as driving force for the reaction:
- formation of an insoluble compound
- formation of water or any other non-ionizing compound
- liberation of a gaseous product.
The true statements are;
<h3>What is a redox reaction?</h3>
We define a redox reaction as one in which a specie is oxidized and another is reduced.
Now;
Eo cell = cell potential = -0.13 V - (+0.34 V) = -0.47 V
n =number of moles of electrons = 2 mole of electrons
K = equilibrium constant
ΔG = change in free energy
Eo cell = 0.0592/n log K
-0.47 = 0.0592/2 log K
log K = -0.47 * 2/0.0592
K = 1.3 * 10^-16
ΔG = -nFEo cell
ΔG = -(2 * 96500 * -0.47)
ΔG = 90.7kJ
