The author states that chemical engineering is one of the most difficult and complex aspects of engineering. Why do you think this is the case?
Why is stoichiometry so important for chemical engineering?
Do you think consumers would notice if process control standards were not met? Explain using an example.
Imagine that you are a chemical engineer who has been given the task of working with a museum curator to create a display case for a rare painting that must be preserved in a controlled environment, meaning elements such as temperature, humidity, exposure to light, etc. must be constantly regulated. What kind of control system would you choose and why?
According to the unit, part of workplace safety is “cultivating a culture of caution.” Explain what this means and how it could be accomplished.
