Flashcards in Chpt. 12, Stoichiochemistry Deck (6):
the branch of chemistry that figures out how much of something can be made, or how much is needed, during a rebellion
the portion of a reaction that is used up first
% yield = (amount of actual value for product) / (amount predicted by chemistry)
when doing equations in stoichiochemistry, a t-chart is generally used; although there are many different types of ways you could potentially do it, the basic idea is that anything on the bottom can cancel out anything on the top, and you have to arrange the equation in such a way that it ultimately cancels out to equal the value of what you want, expressed in the units that you need it expressed in
Experimental error will occur in any chemical reaction that a human being sets up; there has never been a flawless experiment before. Even if the percent yield equals 100%, that doesn't mean it was successful, it just means that the net value in terms of mass of all the various flaws combined equaled what the theoretical yield should actually be.
