Need to review/introduce some ideas about reactions. Stoichiometry WebStoichiometry (/ ˌ s t ɔɪ k i ˈ ɒ m ɪ t r i /) is the relationship between the quantities of reactants and products before, during, and following 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 …

I’m going to use stoichiometry table to show some calculations on different aspects of stoichiometry. by illustrating with examples. WebSTOICHIOMETRY PROBLEMS Most stoichiometry problems follow a set strategy which revolves around the mole. This strategy is: Quantity A → Mols A → Mols B → Quantity B You will be using this strategy or some portion of it most of the time. We'll look at each step of this strategy and then combine these steps for more complicated problems.
