Mg -> MgCl2 -> Mg(OH)2 -> MgO -> Mg(NO3)2

Answer 1

\(Mg+2HCl\rightarrow MgCl_2+H_2\)

\(MgCl_2+2NaOH\rightarrow Mg\left(OH\right)_2+2NaCl\)

\(Mg\left(OH\right)_2\underrightarrow{t^o}MgO+H_2O\)

\(MgO+2HNO_3\rightarrow Mg\left(NO_3\right)_2+H_2O\)

Answer 2

Mg + 2HCl -> MgCl2 + H2

MgCl2 + 2H2O -> Mg(OH)2 + 2HCl

Mg(OH)2 -> MgO + H2O

MgO + 2HNO3 -> Mg(NO3)2 + H2)
