Stoichiometry
The study of the quantitative relationships between the amounts of reactants used and the amounts of products formed by a chemical reaction is called...
What is Stoichiometry
In a reaction, stoichiometry is based on this law.
What is The Law of Conservation of Mass
This indicates that you must determine a limiting reactant.
What is being given amounts of more than one reactant?
The reactant that limits the extent of the reaction is called the
What is limiting reactant
Fe+O2--->Fe2O3
Find the mole ratio of iron to iron(III) oxide?
4:2
What represents not only the number of individual particles but also the number of moles in a chemical equation.
What are the coefficients?
Mole ratios are obtained from the...
What is the balanced chemical equation
The actual yield of a product is measured by this method
What is experimentally
2 Fe + 3 Cl2 --> 2 FeCl3
How many moles of Fe are needed to react with 1.75 moles of Cl2 ?
What is 1.17 moles of Cl2 ?
True or False In any chemical reaction, the mass of the products is the same as the mass of reactants.
What is TRUE
This relates the moles of reactants and products in a chemical reaction
what is a balanced chemical equation
This is the amount of a product calculated using stoichiometry.
What is theoretical yield?
This reactant has a portion remaining after the reaction has stopped.
What is excess reactant
2 KClO3 --> 2 KCl + 3 O2
7.90 g of KClO3 will produce 3.09 g of O2 and _____ grams of KCl.
4.81 g KCl
The mass of each reactant and product is related to one mole in the balanced chemical equation for the reaction by its...
What is molar mass
The reactant that is not used up.
What is excess reactant?
This is the maximum amount of product that can be produced from a given amount of reactant.
What is theoretical yield
Stoichiometry is the study of what type of relationships among the amounts of reactants used and the amounts of products formed.
What is quantitative
This amount of product is rarely produced in a chemical reaction.
What is the theoretical yield
How many grams of NaCl can be produced from 10.0g of NaI?
2NaI + Cl2 --> 2NaCl
round your answer to correct significant figures.
What is 3.90g NaCl
The reactant that gets used up first.
What is limiting reactant?
The ratio of the actual yield to the theoretical yield expressed as a percent is the...
What is percent yield
This determines the amount of product formed in a chemical reaction.
What is the limiting reactant
