4. Criteria and constraints help in deciding which methods to use when extracting useful chemicals from pomace. Which option is an example of an important constraint on a process?
-The desire to have the purest possible product favors the use of water over ethanol.✅?
-Organic solvents are expensive, which limits their use for extracting chemicals.
-Water is expensive, which limits its use for extracting chemicals
- The desire to have the purest possible product favors the use of ethanol over water
The answer is B, Organic Solvents are Expensive, which limits their use for extracting chemicals.
The correct answer is: -The desire to have the purest possible product favors the use of water over ethanol.
The option "The desire to have the purest possible product favors the use of water over ethanol" is an example of an important constraint on a process when extracting useful chemicals from pomace.
To arrive at this answer, we need to understand that criteria and constraints play a significant role in determining the appropriate methods for extracting chemicals from pomace. Criteria are the requirements or goals that need to be met, while constraints are the limitations or factors that restrict the available options.
In this instance, the desire to have the purest possible product is a criteria. This means that achieving a high level of purity is one of the goals or requirements for the extraction process. However, the constraint is that water is favored over ethanol for achieving purity. This implies that using water is a more viable option, as it aligns with the goal of obtaining the purest possible product.
The other options provided in the question also highlight constraints but are not aligned with the desired goal of purity. For example, the option "Organic solvents are expensive, which limits their use for extracting chemicals" highlights a constraint related to cost, but it does not address the requirement of purity. Similarly, the options related to the cost of water or the preference for ethanol over water do not directly relate to the desired goal of purity.
Therefore, the most suitable option that represents an important constraint on the extraction process while aligning with the goal of purity is "The desire to have the purest possible product favors the use of water over ethanol."
