It will take you a LOT of time to learn the material, but ChemE 100 is a course where once it clicks, the rest of the quarter is smooth sailing. I struggled very hard through the first few homeworks, but that's only because it's like learning a new language. By the end of the quarter, you'll become very fluent in the material.
Here is what you'll learn in ChemE 100, along with my advice:
1. You'll start off doing material balances. This part was the hardest for me, but the good news is that every problem you'll encounter will just be variations of what you learn in the first couple weeks, so if you learn these right the first time, you'll struggle a lot less later on. At this stage, I recommend learning how to solve simultaneous equations on your calculator, as that can save you a lot of time on homework and exams.
2. Next you'll learn about how to handle gases, liquids, and solids. I initally had trouble with the gas stuff because I didn't have the intuition for it, but I literally watched this one example video (https://www.youtube.com/watch?v=bs2T5oCfRak) and it clicked for me. At this stage, I recommend learning how to use the solver function on your calculator. Monbouquette will teach you how to find the roots of equations by hand, but you really shouldn't waste time doing it manually when your calculator can do it automatically.
3. Finally, you'll learn to do energy balances. I liked the solution manual's method rather than Monbouquette's, so for this section I actually recommend studying the solution manual very thoroughly. Understand the solution manual's choice of reference conditions VERY WELL, as this will mean the difference between doing three integrals and doing 13 integrals. I recommend learning how to solve integrals on your calculator to save time.
Along the way, you'll learn about ChemE in the real world, including historical events and modern advancements, which is really cool. You'll see that the material you learn in ChemE 100 is the same material that chemical engineers use in the real world.
Overall, ChemE 100 is an excellent introduction to ChemE. If you're interested in doing ChemE tech breadth, I highly recommend this course.
