Answer 1

$\boxed{\bf{\colorbox{pink}{answer:--}}}$

♦️️ Ans. 1
2Mg + O2 ==> 2MgO

♦️️ Ans.2
MgO + H2O ==> Mg(OH) 2

♦️️ Ans.3
Fe + O2 + H2O ==> Fe2O3.

Answer 2

​​​​​​​ ​​ ​ ​​​​​​​​​ ​​​​​​

1) Mg + O2 MgO shows this reaction

Balanced Equation => 2Mg + O2 2MgO.

===========================

​​​​​​​​​​ ​​ ​​​​​​​​​ ​​​​​ ​​​​ ​​​​​​​​​ ​​​​​​​​​.

2) (MgO + H2O → Mg(OH)2),

Mg2+ + Ca(OH)2 → Mg(OH)2 + Ca2+

===========================

​​​​​​​ ​​ ​​​​.

3) Fe(s) → Fe2+(aq) + 2e
