Stoichiometry
To solve any stoichiometry problem involving different substances, you must use this specific ratio derived from the coefficients of a balanced chemical equation.
What is the mole ratio
Often cited as the first true work of science fiction, this 1818 novel was written by Mary Shelley after a "ghost story" competition with Lord Byron and was subtitled "The Modern Prometheus."
What is frankenstein
The substances that start a chemical reaction.
What are reactants?
The type of reaction where two substances combine to form one.
What is a synthesis reaction?
This 6-letter mnemonic device helps students remember that the loss of electrons is oxidation, while the gain of electrons is reduction.
What is OILRIG
In the reaction between 3.0 moles of Hydrogen gas and 1.0 mole of Nitrogen gas to produce Ammonia (NH3), this specific reactant will run out first, effectively stopping the reaction.
What is N2
This 2023 blockbuster film, which became the highest-grossing movie ever directed by a solo woman, came out alongside a christopher nolan movie following Cillian Murphy and a historical event. What is the name given to the release of these two movies together?
What is Barbenheimer
Why chemical equations must be balanced.
What is because mass cannot be created or destroyed?
The classification for AB → A + B.
What is a decomposition reaction?
Although it is the substance being reduced, this reactant is given this title because it enables another substance to lose its electrons.
What is the oxidizing agent
This value is calculated by dividing the mass of the product actually produced in the lab by the maximum mass predicted by stoichiometry, then multiplying by 100.
What is percent yield
If a student calculates a theoretical yield of 25.0 grams for a precipitate but only recovers 20.0 grams after filtration and drying, this is the resulting Percent Yield.
What is 80%
The product in the equation 2H₂ + O₂ → 2H₂O.
What is water?
The type of reaction shown by
Zn + HCl → ZnCl₂ + H₂
What is a single replacement reaction?
In the common laboratory reagent Potassium Permanganate (KMnO4), the Manganese atom possesses this specific oxidation state.
What is +7
2H2 + O2 --> 2H2O
If you start with 10.0 grams of Hydrogen gas (H2) and an excess of Oxygen gas, what is the theoretical yield of Water (H2O) in grams?
What is 89.2 g
You react 27.0 g of Aluminum with an excess of Chlorine gas. What is the theoretical yield of AlCl3 in grams?
What is 133.33 g
The balanced form of Fe + O₂ → Fe₂O₃.
What is 4Fe + 3O₂ → 2Fe₂O₃?
The type of reaction shown by
AgNO₃ + NaCl → AgCl + NaNO₃
What is a double replacement reaction?
In the reaction Zn(s) + Cu2+(aq) --> Zn2+(aq) + Cu(s), this specific element is the one being oxidized.
What is Zinc
Pb(NO3)2 + 2NaCl --> 2NaNO3 + PbCl2
What is the mass of each product when 50.0 g of Pb(NO3)2 react?
What is 25.7 g of NaNO3 and 42 g of PbCl2
This time, you react 54.0 g of Aluminum with 71.0 g of Chlorine gas Cl2. Calculate how many grams of the excess reactant remain after the reaction stops.
What is 35.9 g of Al in excess
Balance the following combustion reaction:
C₃H₈ + O₂ → CO₂ + H₂O
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O?
These are ALWAYS the products of a combustion reaction.
What are H2O and CO2?
When balancing a redox half-reaction in a basic solution, you must first balance for Oxygen using water and then Hydrogen using H+, followed by adding this specific ion to "neutralize" the H+ on both sides.
What is the hydroxide ion OH-
