Explanation:
The separation technique of benzoic acid from diethyl ether is first the usage of the base and then acid.
As, benzoic acid is soluble in diethyl ether and on adding base, it forms sodium benzoate which is soluble in aqueous layer and thus separates from diethyl ether. Acid is then added to convert sodium benzoate in the aqueous layer back to benzoic acid.
But, in the given question, acid is added first and then base and this went wrong.

2. Joe is concerned about the economy. He makes an effort to "buy American," to support the U.S. economy. He reads product literature, looking for evidence of domestic manufacturing, and usually buys American-made products.
Type of learning taking place: operant conditioning.
The stimulus: The U.S. economy.
Desired response: to relieve his concern.
Reinforcement: he engages to an specific behavior
Explanation:
1. Classical Conditioning: If a neutral stimulus or a stimulus that at first elicits no response, like the Miller beer is paired with the American themes, a stimulus that already evokes a reflex response, then eventually the Miller beer will by itself evoke a similar response. Pairing of the Miller beer (CS), with the American theme (UCS) strengthens the connection between the stimuli.
2. Operant Conditioning: Bill is some way concerned about the U.S. economy, he engages in the behavior in which he relieves his concer reading product literature and buying American-made products as instrumens to achieving his concern helping domestic economy.
