Group 2 Reactions As

Front 1

Metal reacts with water and trend?

Back 1

You get metal hydroxide + hydrogen M(s) + 2H2O (l) :M(OH)2(s) +H2(g) .REactions become more vigorous down the group( the metal hydroxide can be s or l depends on its solubility

Front 2

Metal oxide + water gives?

Back 2

Metal hydroxide MO(s) + H2O(l) : M(OH)2 (s)

Front 3

Metal oxide and acid give?

Back 3

Oxides react with acids and so acts as a bases.you get salt and water MO(s) + H2SO4(aq) : MSO4 (aq) + H2O(l)

Front 4

Hydroxides down the group? What alkaline is solution and why?

Back 4

Hydroxides become more soluble as you go down the group.the solutions produce an alkaline solutions as it contains OH- (ph >7)

Front 5

Metal hydroxide and acid produces

Back 5

Salt + water, M(OH)2(s) +2HCL (aq) : MCl2 (aq) +2H2O(l)

Front 6

Carbonates pattern down the group?

Back 6

Carbonated become less double as you go down the group,thermal stability increases down a group

Front 7

Metal carbonate thermal deconposituon :

Back 7

Metal oxide and carbond dioxide.MCO3(s) : MO(s) +CO2(g)
