Obtain, evaluate, and communicate information about how the Law of Conservation of Matter is used to determine chemical composition in compounds and chemical reactions. Use mathematics and computational thinking to balance chemical reactions i. Plan and carry out an investigation to determine that a new chemical has been formed by identifying indicators of a chemical reaction e. Use mathematics and computational thinking to apply concepts of the mole and Avogadro's number to conceptualize and calculate. Use mathematics and computational thinking to identify and solve different types of reaction stoichiometry problems i. Plan and carry out an investigation to demonstrate the conceptual principle of limiting reactants.

Problems of this type are done in exactly the same way as the previous examples, except that a decision is made before the ratio comparison is done. The decision that is made is "What reactant is there the least of? In one experiment, a mixture of 0. Find the limiting reactant, if any, and calculate the theoretical yield, in moles of water. In any limiting reactant question, the decision can be stated in two ways. Do it once to get an answer, then do it again the second way to get a confirmation. We have 1.

When there is not enough of one reactant in a chemical reaction, the reaction stops abruptly. To figure out the amount of product produced, it must be determined reactant will limit the chemical reaction the limiting reagent and which reactant is in excess the excess reagent. One way of finding the limiting reagent is by calculating the amount of product that can be formed by each reactant; the one that produces less product is the limiting reagent. The following scenario illustrates the significance of limiting reagents. In order to assemble a car, 4 tires and 2 headlights are needed among other things. In this example, imagine that the tires and headlights are reactants while the car is the product formed from the reaction of 4 tires and 2 headlights.

Limiting Reagents

Which reactant is the limiting reagent? How many grams of NO are formed? How much of the excess reactant remains after the reaction? How many grams of CO 2 are formed?

 Наличными, прямо сейчас, - сказал Беккер, доставая из кармана пиджака конверт. Я очень хочу домой. Росио покачала головой: - Не могу. - Почему? - рассердился Беккер. - У меня его уже нет, - сказала она виноватым тоном.  - Я его продала. ГЛАВА 33 Токуген Нуматака смотрел в окно и ходил по кабинету взад-вперед как зверь в клетке.

Правда о ТРАНСТЕКСТЕ. Сьюзан понимающе кивнула. Это звучало вполне логично: Танкадо хотел заставить АНБ рассказать о ТРАНСТЕКСТЕ всему миру. По сути, это был самый настоящий шантаж.

 Отпусти меня! - крикнула она, и ее голос эхом разнесся под куполом шифровалки. Мозг Хейла лихорадочно работал. Звонок коммандера явился для него полным сюрпризом. Стратмор решился на. Он жертвует всеми планами, связанными с Цифровой крепостью.

Я хотел, чтобы никто ничего не заподозрил. Любопытным шпикам не придет в голову сесть на хвост преподавателю испанского языка.
