Answer:
Answer is given below.
Explanation:
Anode is that electrode where oxidation occurs. Cathode is that electrode where reduction occurs.
In cell representation, half cell present left to salt-bridge notation
is anodic system and another half cell present right to salt-bridge notation
is cathodic system.
So anode is Cu and cathode is Ag.
oxidation: 
[reduction:
]
-----------------------------------------------------------------------------------------------
chemical equation: 
Oxidizing agent is that species which takes electron from another species. Here
takes electron from Cu. Hence
is the oxidizing agent.
Reducing agent is that species which gives electron to another species. Here Cu gives electron to
. Hence Cu is the reducing agent.
how would it be possible to even be absorbed?? the answer is released.
The specific heat of the unknown metal is 0.859 J/g⁰C.
<h3>Specific heat of the unknown metal</h3>
Heat lost by the unknown metal = Heat gained by water
m₁c₁Δθ₁ = m₂c₂Δθ₂
where;
- c₁ is specific heat of the unknown metal
- c₂ is specific heat of water
(15)(c₁)(99 - 26) = (75)(4.18)(26 - 23)
1095c₁ = 940.5
c₁ = 940.5/1095
c₁ = 0.859 J/g⁰C

I believe it is D. because stoichiometry allows people to determine how much reactant is consumed in a chemical reaction.
