Balancing equations. Not a lot of fun.

E. None of the above

I'd give half credit for answer A,B,C & D

Stoichiometry is the calculation 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 the products can be empirically determined, then the amount of the other reactants can also be calculated.

Stoichiometry ....

Stoichiometry is all of the number-crunching dealing with chemical reactions and is predicated on the mole ratios given in the balanced chemical equation.

As for your answer choices, they seem to be written by someone who isn't all that familiar with stoichiometry. The only one which doesn't remotely have anything to do with stoichiometry is (C) finding the molecular geometry. Depending on the situation, and the methods involved, stoichiometry could come in handy when finding the molar mass of a compound, or when finding the empirical formula of a compound or when finding the amount of a compound. Nonetheless, (B) probably has the best chance of being the "right answer."

Maybe you should actually READ your textbooks and find out for yourself. If you have questions ASK YOUR TEACHER! That's what HE gets paid for!

B. To determine the amount of a substance

(Although that's not a very good answer.)

Measuring stoichis....

Technically, it's about evaluating the results of a chemical reaction so that you get the desired results.

Never heard of it.
