1) 2Mg +O² = 2MgO( combination reaction)
2)Caco³ ......heat.....CaO + Co²(thermal decomposition reaction)
3)Zn +H²So4 =ZnSo4 +H²(displacement reaction)
Hope it may help you

1) Mg+O2-----> Mg2+O = Combination reaction.
2) CaCo3+Heat----->Cao+Co2+H2o = Decomposition reaction.
3) Zn+H2So4-----> ZnSo4 +H2. = Displacement reaction.
