Question

Умоляю , помагитее ！Осуществите цепочку превращений. Mg→H2→H2O→O2→MgO

Answer 1

Mg+2HCl=MgCl2+H2

2H2+O2=2H2O

2H2O=2H2+O2

O2+2Mg=2MgO

Answer 2

Цепочка превращений:

1. Mg → H2 - Magnesium (Mg) reacts with hydrochloric acid (HCl) to produce hydrogen gas (H2) and magnesium chloride (MgCl2) .

2. H2 → H2O - Hydrogen gas (H2) reacts with oxygen (O2) to form water (H2O) through a combustion reaction .

3. H2O → O2 - Water (H2O) can be split into hydrogen gas (H2) and oxygen gas (O2) through a process called electrolysis .

4. O2 → MgO - Oxygen gas (O2) reacts with magnesium (Mg) to form magnesium oxide (MgO) through a combustion reaction.

So, the complete chain of transformations is: - Mg → H2 → H2O → O2 → MgO
