oday was our first real class, and we saw a new subject: STOICHIOMETRY. Technically speaking, stoichiometry is the part of chemistry that deals with amounts and quantities, and we can use it to calculate masses, moles, and percents within a quemical equiation (In short words, stoichiometry is the math behind chemistry).

We also saw the Chemical Yield (or Reaction Yield) is the ammount of product obtained in a chemical reaction; in a chemical reaction it would be like this:

2H2 + O2 (Reactants) ------> 2H2O (Products)


The reason of the recipes (short and easy) was to explain with easier words the stoichiometry; the example we used was the Chocolate Milkshake recipe, and in that part i learned that the quantity of ingredients depended on the amount that was going to be used for all (at least that's what i understood).
