Question

Mg ⟶ MgO⟶Mg(OH)2 ⟶ Mg(NO3)2 ​

Answer 1

2Mg+O2=2MgO

MgO+H2O=Mg(OH)2

Mg(OH)2+2HNO3=Mg(NO3)2

+2H2O

Answer 2

The series of chemical reactions you've listed represents the conversion of magnesium (Mg) into magnesium nitrate (Mg(NO3)2) through various intermediate steps. Here's the balanced chemical equation for each step:

1. Mg to MgO: Mg + 1/2 O2 → MgO

2. MgO to Mg(OH)2 (hydration reaction): MgO + H2O → Mg(OH)2

3. Mg(OH)2 to Mg(NO3)2 (reacting with nitric acid): Mg(OH)2 + 2 HNO3 → Mg(NO3)2 + 2 H2O

So, the overall reaction from Mg to Mg(NO3)2 would be:

Mg + 1/2 O2 + H2O + 2 HNO3 → Mg(NO3)2 + 2 H2O

You can simplify this equation by canceling out the water molecules on both sides:

Mg + 1/2 O2 + 2 HNO3 → Mg(NO3)2

This equation represents the conversion of magnesium (Mg) into magnesium nitrate (Mg(NO3)2) through the specified intermediate steps.
