Question

Mg(NO3) 2- Mg- MgCl2-Mg(OH) 2-MgO​

Answer 1

Ответ:

Объяснение:

Нитрат магния Mg(NO3)2 подвергается термическому разложению на оксид магния, диоксид азота и кислород при нагревании до температуры выше 300^{0}C.

Mg(NO3)2=MgO+NO2+O2

Mg(NO3)2 при разложении будет MgO, но не Mg( может ошибка в схеме?)

Mg + 2HCl = MgCl2 + H2↑

MgCl2 + 2NaOH = Mg(OH)2↓+2NaCl

Mg(OH)2 = MgO + H2O

Answer 2

It looks like you've listed a series of chemical compounds involving magnesium (Mg) and various ions. Let me break down each compound for you:

1. Mg(NO3)2: This is magnesium nitrate. It's composed of one magnesium (Mg) ion bonded to two nitrate (NO3-) ions.

2. Mg: This simply represents a single magnesium atom or ion by itself.

3. MgCl2: This is magnesium chloride. It consists of one magnesium ion bonded to two chloride (Cl-) ions.

4. Mg(OH)2: This is magnesium hydroxide. It's composed of one magnesium ion bonded to two hydroxide (OH-) ions.

5. MgO: This is magnesium oxide. It's a compound where one magnesium ion is bonded to one oxygen (O2-) ion.

Each of these compounds has different properties and uses based on their chemical composition. Is there something specific you would like to know about these compounds?
