-More on Stoichiometry | Wikipedia-
"Stoichiometry...is the calculation of relative quantities of reactants and products in chemical reactions.
Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products leading to the insight that the relations among quantities of reactants and products typically form a ratio of positive integers. This means that if the amounts of the separate reactants are known, then the amount of the product can be calculated. Conversely, if one reactant has a known quantity and the quantity of product can be empirically determined, then the amount of the other reactants can also be calculated....
Here, one molecule of methane reacts with two molecules of oxygen gas to yield one molecule of carbon dioxide and two molecules of water. Stoichiometry measures these quantitative relationships, and is used to determine the amount of products/reactants that are produced/needed in a given reaction. Describing the quantitative relationships among substances as they participate in chemical reactions is known as reaction stoichiometry. In the example above, reaction stoichiometry measures the relationship between the methane and oxygen as they react to form carbon dioxide and water.
Because of the well known relationship of moles to atomic weights, the ratios that are arrived at by stoichiometry can be used to determine quantities by weight in a reaction described by a balanced equation. This is called composition stoichiometry.
Gas stoichiometry deals with reactions involving gases, where the gases are at a known temperature, pressure, and volume and can be assumed to be ideal gases. For gases, the volume ratio is ideally the same by the ideal gas law, but the mass ratio of a single reaction has to be calculated from the molecular masses of the reactants and products. In practice, due to the existence of isotopes, molar masses are used instead when calculating the mass ratio."

FINALLY. My teacher sucks at teaching. All year the whole class has been confused because he moves too fast. We are an honors class, so we are used to fast paced work, but he literally didn't explain ANY of this. He just wrote a bunch of notes on the board super quick and said "Got it? Good." He didn't even explain what stoichiometry was trying to show, so I didn't even understand what I had to do and why. That's why I wound up having to look it up on my own, as I have to pass this class. This video taught me more in fifteen minutes than my teacher has all week, so thank you for making it. It helped me greatly, and I'm finally beginning to understand how to work these problems out. I'll have to show the notes I took to the rest of my class so we can all actually pass the next test.

Im in physical science honors and my teacher is showing me this😭😭😭 He doesn’t teach either. He teaches like his college professors, which don’t teach. They just present a bunch of information to you. All the notes I have on stoichiometry for his class because he didn’t even bother define it is an example of how many cups of eggs do 100 pancakes require. The rest of the time he just spent playing video games. So many people have already gone to the head to say he’s not a good teacher. I have too, my dad has, but nothing works. He just gets worse and worse.. He expects us to already know this and do it ourselves.

I'm taking chem right now, and I thought Stoichiometry is going to kill me, but not after watching this video. It's so simple and easy to understand, why can't our teacher be the same and show us step by step once to actually understand what Stoichiometry means. Thank you so much for this lecture, I'm sure it will help a lot of students that are confused like I was.

This is an interesting comment for me (sorry for the belated reply). My students in higher level math, like you, often struggle a bit, and I always assume it is the difference between manipulating numbers as abstractions (in a math class) versus manipulating numbers that have been given meaning through units and measurement (in chemistry or other science). It seems to require a different part of the brain.

Your pace of speaking and tone is perfect and the animations give a great visual representation. You are a great educator, if only the 10,000s of thousands of dollars i spend at college would afford me a professor with your abilities.
