Before the 20th century, chemists and engineers focused mostly on meeting human needs. During the 20th century, chemical engineers primarily focused on increasing profitability of their processes. Which of the following is a NEW major concern for chemical engineers in the 21st century?
A. Innovating products and processes that are sustainable and good for the environment.
B. Making products and processes faster to serve a larger population.
C. Making products and processes larger to get attention on social media.
D.Reverse engineering products to determine how they were made in the past
How do you know?
Which microscopic properties allow Kevlar and spider silk to
be so strong?
A. large strongly charged atoms and forces within tight coils of molecules
B. strong chains of molecules that form tight balls
C.large strongly charged atoms with strong intermolecular forces between layers
D. strong chains of molecules and strong intermolecular forces between
layers
The final three choices are pretty silly. We are faced with an environmental crisis and everyone working on chemical engineering for example is trying to reduce CO2 and Methane and other results of our processes.
I do not know the answer to the second one, not my field. However I would guess:
D. strong chains of molecules and strong intermolecular forces between
layers
BUT heck your text. The answer must be there.
I looked over my test a few times and it literally doesn’t say it. I’ll look again ig
Not my field either but I think D is the most likely correct choice.
To determine the answer to this question, we need to understand the progression of concerns for chemical engineers over time.
Before the 20th century, the focus of chemists and engineers was mainly on meeting human needs. This means they were primarily concerned with developing products and processes to fulfill basic requirements and improve quality of life.
During the 20th century, the primary focus of chemical engineers shifted towards increasing profitability. This means that their main concern became finding ways to optimize processes and reduce costs to maximize profits.
In the 21st century, a new major concern has emerged for chemical engineers. Taking into account the context and the current global challenges, option A, innovating products and processes that are sustainable and good for the environment, is the most likely answer.
Therefore, the correct choice for the new major concern for chemical engineers in the 21st century is:
A. Innovating products and processes that are sustainable and good for the environment.
