A reaction that can go backwards and forwards at the same time. Reactants make products while products make reactants.
What is a reversible reaction?
100
An element that, when written in it's "elemental" form (by itself), is always accompanied by a subscript of 2.
What is a diatomic element?
100
The species that runs out/is used up first in a chemical reaction.
What is the limiting reactant/reagent?
200
This type of reaction: Li + KCl --> K + LiCl.
What is a single replacement reaction?
200
This type of reaction: Mg²⁺ + 2e⁻ --> Mg (Name as either oxidation or reduction).
What is a reduction?
200
A state in which the forward and reverse reactions are occurring at the same rate.
What is equilibrium?
200
The chemical formula for sodium phosphate, written so the overall charge of the compound is neutral.
What is Na₃PO₄?
200
When comparing one species to another using stoichiometry, it is possible to look at the gram-to-gram ratio or the mole-to-mole ratio. (True or false).
What is false?
300
The type of reaction that only has one reactant.
What is a decomposition?
300
The thing that gets reduced/does the oxidizing in a redox reaction.
What is an oxidizing agent?
300
The species (using the graph on the board) that is more abundant at equilibrium.
What is species B?
300
The balanced equation for the combustion methane (CH₄) to produce water and carbon dioxide.
What is CH₄ + 2 O₂ --> 2 H₂O + CO₂?
300
If I have the same number of moles of Al and Cl₂, which is the limiting reactant in this equation: Al + Cl₂ --> AlCl₃ (Hint: balance the equation!)
What is chlorine?
400
The tool we use to determine if a single replacement reaction will occur.
What is the activity series?
400
The half reaction going from O²⁻ to O-.
