<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

Answer:
The relative humidity in Raleigh, NC
You can search it up online. Search up what is climate change and it will give you "the weather conditions prevailing in an area in general or over a long period." (On bing)

<span>1) </span><span>Deduce
the two masses and see the amount of water was driven off when heated: </span><span>
<span>5.03 g -
4.23 g = 0.8 g H2O given off </span>
<span>2) Change
mass from grams to moles of H2O: </span>
<span>0.8 g H2O
/ 18 g H2O in 1 mole = 0.044 mol H2O </span>
<span>3) Change
left over mass to moles of BaCl2 .</span></span>
<span>
<span>4.23 g
BaCl2 / 207 g BaCl2 in 1 mol = 0.021 mol BaCl2 </span>
<span>4)Find
the ratio of mol H2O to mol BaCl2: </span>
<span>0.044 mol
H2O : 0.021 mol BaCl2 </span>
<span>5) The
resulting ratio is 2:1 so two H2O for each BaCl2, thus, the hydrate was named: </span>
<span>Barium
chloride di-hydrate</span></span>

Answer:
in metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. ... Metals are shiny.
