Sketch a graph showing the trends of the properties shown in the table below as you go down Group 2 and explain the general trends.
Don’t worry about the Melting point
Atomic and physical properties
Reactions with Oxygen and Water and dilute acids
What colour do they burn in Oxygen?
Design an experiment to discover the trend of how thermally stable the carbonates are as you go down the group. Tabulate your results. Write balanced equations for this thermal decomposition.
FB1: Calcium Carbonate FB2: Magnesium Carbonate
Extension: Can you explain why?
Research to discover the trend of how thermally stable the nitrates are as you go down the group. Write balanced equations for this thermal decomposition
Behaviour of oxides, hydroxides and carbonates with water and dilute acids
Research how the Group 2 oxides, hydroxides and carbonates react with water and dilute hydrochloric acid, nitric acid and sulfuric acid
In the table summarise the trends and write down balanced equations
Link the trends in solubility to pH
Explain in more detail the behaviour with dilute sulfuric acid
Design a leaflet explaining the use of group 2 elements in industry specifically the use of Magnesium oxide as refractory lining material and lime in agriculture
