What is the thermite reaction?
Transcript of What is the thermite reaction?
: Describe the reactivity series
: Describe with an equation what happens in the thermite reaction
: Use the reactivity series to predict displacement reactions
What is a displacement reaction?
Reactivity, displacement, exothermic, oxide
Aluminium is more reactive than iron
It displaces iron from its compounds
Aluminium + iron oxide -> aluminium oxide + iron
The aluminum has displaced iron from its oxide compound
: The Reactivity Series
Reactions between metals, water, air and acid can be used to put metals into a reactivity series
You will be set in teams of 3 or 4.
Using the clues and what you know about these metals you need to put them in order of reactivity.
1) Emily O'C, Sarah, Josh, Daniel
2) Tate, Tim, Guy, Louie
3) Abi, Daisy, Jack K
4) Tom, Seth, Alissa, Ella
5) Sara, Lucy, Lucas, Curtis
6) Ethan, Emily C, Merle
7) Jimmy, Alex, Jack B, Milovan
1) Potassium, Sodium, Calcium, lithium
reaction of potassium with water:
Reaction of lithium in water:
Reaction of calcium in water:
2) Zinc, magnesium, lead
Zinc reaction in acid:
Lead fact: Lead was used to make pipes by the ancient romans, some historians argue that the slow reacton between the water and the lead caused disease and the fall of rome
3) Copper, gold, silver
Copper and oxygen reaction:
Gold in hydrochloric acid:
2500 year old silver
Correct Series in order of most reactive to least
1) Potassium, Sodium, Lithium, calcium
2) Magnesium, zinc, lead
3) Copper, Silver, Gold
Which is the odd one out?
Can you work out the name of the compound?
Zinc is more reactive than lead
Write down the word equation for the thermite reaction
Complete the symbol equation:
iron + copper oxide -> iron oxide + copper
2Fe(s) + 3CuO(s) ->
Odd one out
What is the most reactive metal?
What is the least reactive metal?
This reaction is called the thermite reaction
Prepare to write a description of the thermite reaction
Write a description of the thermite reaction
