Answer:
In the reaction between p-aminophenol and acetic anhydride to form acetaminophen, 4.5 ml of water were added. This was done to recover the product out the container. Water was used as a means of carrying out the product out the container. However, it should be noted that we would want a small amount to be added in order to avoid the product dissolving onto it.

Answer:
true
Explanation:
osmosis is a special case of diffusion. diffusion occurs across a semipermeable membrane and only the water or other solvent moves. Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution.
Answer:
is usually structurally similar to the substrate.
Explanation:
Competitive inhibitors resemble normal substrate and binds to enzyme at the active site usually and prevents substrate from binding.
Active sites are main location for the substrate-enzyme binding. These sites involve weak as well as reversible bonds between the substrate and the enzyme. These inhibitors bind to the active sites and form weak and reversible bonds. Competitive inhibitors can be dissociated from active site by increasing concentration of the substrates. Substrates has to compete for active site and displace the bound competitive inhibitors.
<u>Hence, correct option is - is usually structurally similar to the substrate.</u>
