What type of reaction am I?
This type of reaction occurs when something is burning
Combustion reaction
Decomposition reaction
Temperature
concentration
pressure/volume
catalyst
surface area
Crushing a reactant into powder will increase or decrease its rate of reaction?
Increase
This type of reaction occurs when a complex substance breaks down into multiple simpler substances
Decomposition reaction
What type of reaction?
Iron reacts with oxygen to make rust
Synthesis reaction
What happens to the rate of reaction when you decrease the temperature of the reactants?
Rate of reaction decreases
What type of reaction?
Calcium carbonate is heated by a bunsen burner, breaking down into carbon dioxide and Calcium oxide
Decomposition reaction
This type of reaction occurs when an acid and a base neutralise each other to make a water and a salt
Neutralisation reaction
What type of reaction?
Sodium bicarbonate is put on an acid spill to safely neutralise it before cleaning up.
Neutralisation reaction
What happens when you introduce a catalyst to a chemical reaction?
The activation energy of the reaction is decreased, causing collisions to be more likely to cause reactions, increasing rate of reaction.
This type of reaction occurs when you mix two aqueous solutions and they react to make an aqueous solution and a solid
Precipitation reaction
This type of reaction occurs when a more reactive substance displaces/replaces a less reactive one in a substance
Displacement reaction
What type of reaction?
Mr Newbury lights a match, burning the red phosphorous head to produce light and heat
Combustion reaction
Explain what collision theory is
Theory that reactions happen when reactant particles collide with correct orientation and a minimum amount of energy/speed.
What is it called when a particle is hit by a neutron, splitting into two smaller particles and releasing energy.
Nuclear Fission
