\(Mg+\dfrac{1}{2}O_2\xrightarrow[]{t^o}MgO\)
\(MgO+2HCl\rightarrow MgCl_2+H_2O\)
\(MgCl_2+K_2CO_3\rightarrow2KCl+MgCO_3\downarrow\)
\(MgCO_3+2HNO_3\rightarrow Mg\left(NO_3\right)_2+H_2O+CO_2\uparrow\)
\(Mg\left(NO_3\right)_2+2KOH\rightarrow2KNO_3+Mg\left(OH\right)_2\downarrow\)
a) 2Mg + O2 ----------to---------> 2MgO
MgO + 2HCl -----------> MgCl2 + H2O
MgCl2 + K2CO3 ---------> MgCO3 + 2KCl
MgCO3 + 2HNO3 --------> Mg(NO3)2 + H2O + CO2
Mg(NO3)2 + 2KOH ----------> Mg(OH)2 + 2KNO3

4Na + O2 -----to→ 2Na2O
Na2O + CO2 ---to→ Na2CO3
Na2CO3 + H2SO4 → Na2SO4 + CO2 + H2O
Na2SO4 + BaCl2 → BaSO4 + 2NaCl
(1) 2Na + Cl2 → 2NaCl
(2) Cl2 + H2 → 2HCl
(3) 3HCl + Fe(OH)3 → FeCl3 + 3H2O
