Stoichiometry
What uses relationships between reactants and products to determine quantitative information in a chemical reaction?
Stoichiometry
What is the reactant that is used up first in a chemical reaction?
Limiting reactant
What is the amount of a substance produced according to the stoichiometric calculation called?
Theoretical yield
What is used to compare different molecules or compounds?
The mole
True or False: The reactant with fewer grams is the limiting reactant.
False
What is the amount of substance that is produced in an experiment called?
Actual yield
What number is used when converting to or from moles to particles?
Avogadro's number
What are the reactants that have enough to complete the reaction called?
Excess reactant
What is the molar mass of carbon monoxide?
28.01 grams per mole
How do we start the process of converting the grams of H2 to moles of H2?
Using the molar mass of H2
True or False: To find the limiting reactant, you must divide the moles of each reactant by its coefficient in the balanced equation.
True
In an experiment, 15 grams of NaCl were produced. The theoretical yield was 25 grams. What is the percent yield?
60%
How many moles of sodium chlorate are needed to produce 46.8 grams of sodium chloride?
2 NaClO3 → 2 NaCl + 3 O2
0.8 mol NaClO3
Given the balanced equation below, how many grams of H2O will be produced if 25.4 g LiOH reacts with 64.8 g CO2?
2LiOH + CO2 🡪 Li2CO3 + H2O
9.56 grams of H2O
According to the chemical equation, 32 liters of O2 will be produced in a reaction. However, 30 liters are produced. What is the percent yield?
93.8%
