Answer the following question given this paragraph: Esters are neutral compounds, unlike the acids from which they are formed. In typical reactions, the alkoxy (OR) group of an ester is replaced by another group. One such reaction is hydrolysis, literally "splitting with water. " The hydrolysis of esters is catalyzed by either an acid or a base. Acidic hydrolysis is simply the reverse of esterification. The ester is heated with a large excess of water containing a strong-acid catalyst. Like esterification, the reaction is reversible and does not go to completion. Q: What reaction means, literally, "splitting with water"? Choices: - aqueous - hydroxis - fission - hydrolysis A:
(Answer)
hydrolysis

Answer the following question given this paragraph: There is always a slightly negative pressure within the thoracic cavity, which aids in keeping the airways of the lungs open. During inhalation, volume increases as a result of contraction of the diaphragm, and pressure decreases (according to Boyle's Law). This decrease of pressure in the thoracic cavity relative to the environment makes the cavity less than the atmosphere (Figure 39.16a). Because of this drop in pressure, air rushes into the respiratory passages. To increase the volume of the lungs, the chest wall expands. This results from the contraction of the intercostal muscles, the muscles that are connected to the rib cage. Lung volume expands because the diaphragm contracts and the intercostals muscles contract, thus expanding the thoracic cavity. This increase in the volume of the thoracic cavity lowers pressure compared to the atmosphere, so air rushes into the lungs, thus increasing its volume. The resulting increase in volume is largely attributed to an increase in alveolar space, because the bronchioles and bronchi are stiff structures that do not change in size. Q: There is always a slightly negative pressure within what cavity, helping keep the airways of the lungs open? Choices: - anal - cervical - spinal - thoracic A:
(Answer)
thoracic
