-Na2O + H2O 2 NaOH đúng

-Zn+O2Zn O2 (sai vì Zn hóa trị 2, 2Zn+O2->2ZnO)

-2Al+3Cl22AlCl3 đúng

-P+2O2PO4 (sai vì 4P+5O2→ 2P2O5)

-CaCO3CaO+CO2 (thiếu nhiệt độ)

Mg + 2HCl => MgCl2 + H2

2Al + 3H2SO4 => Al2 ( SO4 )3 + 3H2

CuO + H2 => Cu + H2O

2Mg + O2 => 2MgO

2Na + H2SO4 => Na2SO4 + H2

Cu + 2AgNO3 => Cu ( NO3 )2 + 2Ag
