Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

Percent yield of a product is a measure of a reaction's
efficiency
The actual yield of a product is
measured experimentally
What is the mass IN GRAMS of O2 (g)

balance.

How many moles of butane are represented by the equation?

How many molecules of carbon dioxide are represented by the equation?

Limiting a reactant is often accomplished by
using an excess of another reactant
Mole ratios for a reaction are obtained from the
balanced chemical equation
The study of the quantitative relationships among the amounts of reactants used and the amounts of products formed by a chemical reaction is called
stoichiometry
In a balanced chemical equation, the numbers of individual particles and the number of moles of particles are represented by the
coefficients
Stoichiometry is based on the law of conservation of
mass
The ratio of the actual yield to the theoretical yield expressed as a percent is called the
percent yield
The amount of product actually produced by a chemical reaction is called the
actual yield
The reactant that limits the extent of the reaction is called the
limiting reactant
