2.15, 2.17 Reactivity Series

Reactivity Series

Reactions to remember:

Metal + Water --> Metal hydroxide + hydrogen
Metal + hydrochloric acid --> metal chlride + hydrogen
Metal + sulphuric acid --> metal sulphate + hydrogen

Displacement Reactions

 A more reactive metal is able to displace a less reactive metal from its solution

e.g. Magnesium + iron sulphate --> magnesium sulphate + iron
               Mg      +     FeSO4       -->        MgSO4              +  Fe

Series

 Potassium                                                               ** Really reactive metals are found in compounds
Sodium
Lithium
Magnesium
Aluminium
Carbon (for metal extraction)
Zinc
Iron
Tin
Lead
Hydrogen (tells us if a metal reacts with water)
Copper
Silver
Gold
Platinum

States of matter: Solid - Difficult to compress - Fixed shape - Fixed volume  - Particles are closely packed Liquid - Molds shape to container  - Fixed volume  - Cannot be compressed  - Particles far apart  Gas - Particles far apart - No fixed shape - No fixed volume  - Easy to compress

1.35 understand how to carry out calculations involving gas volumes and the molar volume of gas

By Anonymous -
At standard temperature and pressure, one mole of any gas will occupy 24000 cm3; also known as 24dm3. Calculating molar volume from mass Example: 976 cm 3 of oxygen was found to have a mass of 1.3 g Calculate the molar volume of oxygen, under these conditions. Volume = mass x no. of moles Mass of oxygen, O 2 , = 32.0 g. Volume of 1 g = 976 ÷ 1.3 Hence, 32 g = (976 ÷ 1.3) × 32 = 24024 cm 3 Answer: 24.0 is the volume of 32.0 g of O 2 .

Oxidization  Metals and metal oxides  Example  Magnesium + copper oxide --> magnesium oxide + copper Magnesium has been  oxidized to magnesium oxide   Copper has been reduced to copper Copper oxide is the oxidizing agent - it oxidizes but gets reduced in the process Mg is the reducing agent - it reduces the CuO to Cu but gets oxidized in the process e.g. Ca + ZnO --> CaO + Zn
