Chemistry: Year 9 Term 4: Reactivity Series

Define "ore" (2)
Rocks containing enough metal that it is economical to extract them
1 of 11
Define "oxidised" (2)
1) With O2 added 2) Lost electrons
2 of 11
Define "reduced" (2)
1) With O2 removed 2) Gained electrons
3 of 11
What is the reactivity series? (3)
A list of metals, hydrogen and carbon in order of reactivity from highest at top to lowest at bottom
4 of 11
Metal + water --> (2)
Metal hydroxide (metalOH) + hydrogen (H2)
5 of 11
Metal + acid --> (2)
A salt (metal chloride, sulphate or nitrate) + hydrogen (H2)
6 of 11
Why can Al be used outside with corroding despite its reactivity? (2)
It is covered in a layer of aluminium oxide which prevents it from reacting further
7 of 11
What are the three most reactive metals? (3)
Potassium, Sodium, Lithium
8 of 11
What are three least reactive metals? (3)
Platinum, Gold, Silver
9 of 11
What occurs in a reaction between acid and the alkali metals? (2)
It reacts so vigorously it explodes
10 of 11
What is the test to prove H2 is produced? (2)
Squeaky pop - w/lit splint it makes a noise
