Answer: 1
Explanation: Step by Step
Description: The standard enthalpy of reaction is the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states.
Answer: Option (d) is the correct answer.
Explanation:
An oxidizing agent is defined as the substance that itself gains an electron and helps in oxidation of another substance.
For example,
Here, is the oxidizing agent.
Also, a substance with more positive value of electrode potential will be the strongest oxidizing agent. Whereas a substance with more negative value of electrode potential will be the strongest reducing agent.
Therefore, out of the given options has the highest positive value of electrode potential so, is the strongest oxidizing agent.
Q = mCΔT
ΔT = 29.2 - 20 = 9.2 °C
Q = 120 x 4.184 x 9.2
Q = 4,619.1 Joules
