Question

a) Classify the following reactions into different types, giving reason
D) CaCO3(s) --HEAT---> Cao(s) + CO2(g)
ii) Mg(OH)2(aq) + H2SO4(aq) -----> MgSO4(aq) + 2H20(1)​

Answer 1

CaCO3(s) --HEAT---> Cao(s) + CO2(g)

This reaction is an example of thermal decomposition

Mg(OH)2(aq) + H2SO4(aq) -----> MgSO4(aq) + 2H20(1)​

This reaction is an example of double displacement reaction

Hope this helps

Have a great day ;)
