Answer and Explanation:
A) Unconditioned Stimulus- The onion
B) Unconditional Response- Crying
C) Conditioned Stimulus- Chiming clock
D) Conditioned Response- Crying
In the above scenario( an example of classical conditioning), Elmer has been conditioned by the continuous iterations of having to cook everyday by 5pm. He cooks with onions by 5pm around the same time his uncle's clock chimes five times. He cries/has teary eyes(unconditioned response) because of the response to the onions(unconditioned stimulus) around the same time the clock chimes five times thereby conditioning his response so that even when the onions isn't there/he isn't even cooking, he tears up to the clock chimes around 5pm. The clock is therefore a conditioned stimulus and there is a conditioned response of crying.
The unconditioned response to an unconditioned stimulus happens naturally(an instinct) because it is a biological response to the onions, not conditioned.

Answer:
Option 3. The catalyst does not affect the enthalpy change (
) of a reaction.
Explanation:
As its name suggests, the enthalpy change of a reaction () is the difference between the enthalpy of the products and the reactants.
On the other hand, a catalyst speeds up a reaction because it provides an alternative reaction pathway from the reactants to the products.
In effect, a catalyst reduces the activation energy of the reaction in both directions. The reactants and products of the reaction won't change. As a result, the difference in their enthalpies won't change, either. That's the same as saying that the enthalpy change of the reaction would stay the same.
Refer to an energy profile diagram. Enthalpy change of the reaction measures the difference between the two horizontal sections. Indeed, the catalyst lowered the height of the peak. However, that did not change the height of each horizontal section or the difference between them. Hence, the enthalpy change of the reaction stayed the same.
