Chemical changes
This process happens when a metal gains oxygen.
What is oxidation?
These reactions transfer energy to the surroundings.
What are exothermic reactions?
Increasing the temperature increases the rate of reaction because the particles have more...
What is kinetic energy?
What piece of equipment measures volume
measuring cyclinder
What are the sub-atomic particles with not charge called
what are neutrons?
A more reactive metal can do this to a less reactive metal from its compound.
What is displacement?
In this type of reaction, the temperature of the surroundings decreases.
What is an endothermic reaction?
This theory explains reactions in terms of particles colliding.
What is collision theory?
If I add marbles and acid together which gas is produced
Carbon Dioxide
Who came up with the atomic model of the atom after his gold leaf experiment
Who is Rutherford?
This metal is extracted by electrolysis because it is more reactive than carbon.
What is aluminium?
This type of bond energy change happens when bonds are broken.
What is an exothermic reaction?
Increasing this in a gas reaction causes particles to collide more often.
What is pressure?
This graph feature shows the reaction has stopped.
What is the graph leveling off (plateau)?
Type of bonding that is sharing electrons
Covalent
The pH of a strong alkali is usually in this range.
What is pH 13–14?
This type of bond energy change happens when bonds are broken.
What is energy taken in (absorbed)?
Increasing this in a liquid means the particles collide more often with energy equal to or greater than activation energy
What is concentration?
In the disappearing cross experiment, sodium thiosulfate reacts with this acid.
What is hydrochloric acid?
A carbon fullerene that is good at medication delivery
What is a bucky ball?
H⁺ + OH⁻ → H₂O ?
What reaction is this representing?
What is neutralisation?
Bonds broken-bonds made
Catalysts increase reaction rate by lowering this.
What is activation energy?
This piece of equipment is often used to measure gas volume.
What is a gas syringe?
How can graphite conduct electricity
what are delocalised electrons in graphite?
