Answer:</h3>
= +0.43 V
<h3>
Explanation:</h3>
The two standard reduction potentials are;
Fe³⁺(aq) + e⁻ → Fe²⁺(aq) E₀ = +0.77 V
Cu²⁺(aq) + 2e⁻ → Cu(s) E₀ = +0.34 V
The overall reaction is;
Fe³⁺(aq) + Cu(s) → Fe²⁺(aq) + Cu²⁺(aq)
To calculate the standard cell potential of the overall reaction, we use the equation;
Ecell = E redu, cathode - E red, anode
From the reaction; Copper lost electrons to form copper ions (Cu²⁺) (Oxidation) while Fe³⁺ gained electrons to form Fe²⁺ (reduction)
Therefore;
E cell = + 0.77 v - (+0.34 v)
= + 0.43 V
Hence, the standard cell potential of the overall reaction is +0.43 V

Answer : 7.87 X
.
Explanation : To find the fraction of schottky defects in the given lattice of CsCl,
we use the formula,
on solving with the given values ,
and T as 645 + 273 K and rest are the constants.
we get the answer as 7.87 X
.
The answer is A.)The final pressure of a gas is directly proportional to volume and temperature change.
1. You can use the formula V1/ T1 = V2/T2
Solve for V2 give than V1= 10.0 L, T1= 25 C= 298 K, T2= 10 C= 283 K.
(10.0L/298K)= V2/283K------> V2= 9.50 L.
I cant see the answer there.. weird!
2. you can use the formula P1V1= P2V2
solve for V2 given than P1= atm, V1= 2.0 L, P2= 300 atm.
(1atm)x(2.0L)= (300atm)V2----->0.00667 atm.
so answer is A.
