Posing Questions/ notes-

Think about the molecules as humans, the work that you put in don't often means that you will get the perfect result that you want. Also, even though life is considerably long, not everyone gets to find their perfect partner.

Molecules are the same.

The condition for them to react with each other has to be in the right condition (temperature, energy, orientation) so that the "yield" of desired product will be higher.

We can often use methods such as increasing the concentration of reactants or using heat to speed up completion, but normally we do not get the total amount of product yield calculated from the balanced chemical equation.

Percent Yield =

[(How much product you get in grams)/ (the amount of products that you should get calculated by equilibrated chemical equation)]*100%

*The premise of percent yield is to know how much product has been formed, scientists use this to adjust conditions of their experiment accordingly.
