With the correct choice of acid, acid hydrolysis of ethanamide could produce A) ethanoic acid and ammonium chloride. B) ethanoic
Stells [14]

Answer:

A) Ethanoic acid and ammonium chloride.

Explanation:

Amides go through acid hydrolysis to produce carboxylic acid and ammonia by heating in aqueous acid. The acid hydrolysis reaction is produced through the <u>nucleophilic addition of water to the protonated amide</u>, then comes the transference of a proton from the oxygen to the nitrogen to make nitrogen a better leaving group, and finally, the subsequent elimination (see attachment).

In this case, the products formed with the reaction of ethanamide and aqueous HCl will be <u>ethanoic acid and ammonium chloride</u>.

Suppose a student repeats a measurement two times and then calculates the standard deviation. Because the standard deviation is
Valentin [98]

Answer:

The correct answer is option B, that is, a small standard deviation suggests greater precision.

Explanation:

A determination of precision is a standard deviation, it is more reliable in comparison to mean deviation. The square root of the total of the squares of the deviations divided by the degree of freedom for the array of measurements is known as standard deviation.  

The precision of low standard deviation value is more as the results or observations demonstrated by the low standard deviation are more close to average.
