Reaction Types
A + B → AB is the general formula for this type of reaction
What is a composition reaction?
A solid formed when two aqueous solutions react.
What is a precipitate?
Acid + Base → Salt + Water. This general formula represents this reaction type.
What is a neutralisation reaction?
This natural process in the cider gum sap produces ethanol and carbon dioxide.
What is fermentation?
The speed at which reactants are converted into products.
What is the rate of reaction?
In this reaction, one compound breaks into two or more products.
What is decomposition?
A tool that chemists use to predict if a precipitate forms
What is a solubility chart?
The volume from the burette required to reach the endpoint.
What is a titre in titration?
This common gas makes up about 78% of Earth’s atmosphere.
(Hint: it’s colourless, odourless, and non-reactive.)
What is nitrogen?
The particles must collide with enough energy and in the correct orientation.
What is required for a collision between reactant particles to be successful?
CuSO₄ + Zn → ZnSO₄ + Cu demonstrates this type of reaction.
What is a single displacement reaction?
A precipitation reaction, where two aqueous solutions form an insoluble solid, is this type of chemical reaction.
What is a double displacement reaction?
This piece of glassware is clamped vertically and used to deliver a measured volume of solution during titration.
What is a burette?
This metal is liquid at room temperature and was once used in thermometers.
What is mercury (Hg)?
This increases particle speed and and therefore collision energy during a reaction.
What is the relationship between temperature and collision theory?
A colour change, gas, or precipitate may indicate this has occurred.
What is a chemical reaction?
An ion that remains unchanged during precipitation reactions?
What is a spectator ion?
Titres within ±0.10 mL of each other.
What are concordant titres?
This everyday chemical compound makes up about 60% of the human body and covers 70% of Earth’s surface.
What is water (H₂O)?
Can lower the activation energy required for a reaction and speed up a reaction in the process
What is a catalyst?
Fe(OH)3 + NH4Cl ---- FeCl3 + NH4OH.
This chemical reaction is an example of ______?
What is an example of double displacement?
When no more solute can dissolve in a solvent at a given temperature, the solution is described as this.
What is a saturated solution?
Two acids have the same molar concentration, but this one reacts faster and conducts electricity better because it fully ionises in solution.
What is a strong acid?
This company was founded on September 4, 1998.
What is google?
A catalyst increases the rate of a reaction by providing an alternative reaction pathway with a lower one of these.
What is activation energy?
