Question

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?(1 point)

The desire to have the purest possible product favors the use of water over ethanol.

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.

Organic solvents are expensive, which limits their use for extracting chemicals.

Answer 1

Organic solvents are expensive, which limits their use for extracting chemicals.

Explanation: cost is a constraint (limits feasible options), whereas statements about preferring purity (water vs ethanol) are criteria/preferences.
