Engineers are developing a process to produce phosphorus pentachloride. Which two criteria are the most essential when developing this process?
A. Any additional products of the process should also have
commercial uses so they can be sold to various industries.
B. The process should maximize the production of products from
reactants.
O C. The workers who operate the process should be able to run the
equipment safely.
D. All processes should involve technologies that produce the
product in a way that is similar to how it was produced before.

Options B and C are the two criteria that are most essential

Explanation:

When trying to develop a novel process, it is important that the new process involves the use of equipment that can be operated safely by workers so as to prevent death or injury in the cause of handling this equipment. If this equipment is seen not to be safe or cannot be handled safely by workers, it can/will force workers to previous or alternative methods that require more safe equipment.

Also, the process must be able to maximize the most of the reactants, i.e the process must be able to convert a good percentage of the reactants into the desired product (phosphorus pentachloride) since that is the focus. This will also lead to reduction of byproducts produced which could be useful or otherwise (a loss).

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
