1The higher the position of the metal in order of reactivity the?
more reactive it is
2What is the order of reactivity from most to least?
Potassium -> Sodium -> Calcium -> Magnesium -> Carbon -> Zinc -> Iron -> Lead -> Hydrogen -> Copper -> Silver
3Metals above Carbon will react with and not react with what?
React with cold water, steam & acid
4Metals above Hydrogen will react with and not react with what?
React with steam & acid but not with cold water
5Do metals below Hydrogen react with acids, steam or cold water?
No
6How can you extract metals below carbon in the reactivity series from their molten ores?
By heating it with carbon (a reducing agent)
7How can you extract metals above carbon in the reactivity series from their molten ores?
By Electrolysis
8Metal Oxide + Carbon gives?
Metal + Carbon Dioxide
9Metal + Steam/Cold Water gives?
Metal Oxide + Hydrogen
10Metal + Acid gives? (assuming the metal is above hydrogen)
Metal salt + Hydrogen
11What is a displacement reaction?
When a more reactive metal displaces a less reactive one from its salt solution
12$Fe (s) + CuSO_4 (aq)$ gives?
$FeSO_4 (aq) + Cu (s)$
13Which solid metals are grey in colour?
Magnesium, Zinc, Lead & Iron
14Which solid metal is reddish-brown in colour?
Copper
15Which metal salt solutions are colourless?
Magnesium, Zinc & Lead
16What colour is copper salt solution?
Blue
17What colour is Iron (II) salt solution?
Green
18What colour is Iron (III) salt solution?
Yellow/Orange/Brown
19What must be present for metals to rust?
Oxygen (in the air) & water (any state)
20How does a protective layer prevent rusting?
It prevents oxygen and water from coming into contact with metals hence preventing rusting
21What are some examples of protective layers to prevent rusting?
Painting, Oiling/Greasing, plastic covering & electroplating (aka tin/chrome plating)
