<h3>
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
Metal is 1 of the best electrical conductors and this because , heat travels fast and locks heat inside of it . It will not transfer heat to anything other than the metal itself
Answer:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
Explanation:
We are to give the reaction expression for this displacement reaction.
Reactants = copper and silver nitrate solution
Products = silver and copper (II) nitrate
Copper = Cu
Silver nitrate solution = AgNO₃
Silver = Ag
copper (II) nitrate = Cu(NO₃) ₂
So:
Cu + 2AgNO₃ → 2Ag + Cu(NO₃)₂
If a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced. Details about number of moles can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated as follows:
The following chemical equation was given as follows:
C3H8 + 502 = 3CO2 + 4H₂O
1 mole of C3H8 produced 3 moles of carbon dioxide
Hence, 3.53 moles of C3H8 will produce 3.53 × 3 = 10.59 moles of CO2.
Therefore, if a student burns 3.53 moles of C3H8, 10.29 moles of carbon dioxide would be produced.

Answer: 2.00 V
Explanation:
The balanced redox reaction is:
Here Al undergoes oxidation by loss of electrons, thus act as anode. Copper undergoes reduction by gain of electrons and thus act as cathode.
Where both are standard reduction potentials.
Thus the standard cell potential is 2.00 V
