Answer: The for the reaction is 212 kJ
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The net reaction is
The intermediate balanced chemical reaction will be,
(1)
(2)
(3)
Therefore, the for the reaction is 212 kJ
<span>When you squeeze an air-filled balloon, you are decreasing its volume. Imagine a ball going at a constant speed between two walls that are 10 feet apart vs. 1 feet apart. You can imagine that when the walls are only 1 feet apart, the ball will hit the walls more times. Therefore, the answer is A. You are correct.</span>
