Question

Mg =MgCl2=Mg(OH) 2=MgSO4​

Answer 1

Объяснение:

1)Mg+Cl2=MgCl2

2)MgCl2+2NaOH=Mg(OH)2+2NaCl

4)Mg+H2SO4(конц.)=MgSO4+H2O+H2S

Answer 2

The equation you've provided is not accurate. Let's correct it and discuss the correct chemical formulas and names for each compound:

1. Mg: This represents elemental magnesium, which is a metal.

2. MgCl2: This is magnesium chloride, which is an ionic compound formed when magnesium (Mg) reacts with chlorine (Cl). It consists of one magnesium ion (Mg^2+) and two chloride ions (Cl^-).

3. Mg(OH)2: This is magnesium hydroxide, which is also an ionic compound. It forms when magnesium reacts with hydroxide ions (OH^-). It consists of one magnesium ion (Mg^2+) and two hydroxide ions (OH^-).

4. MgSO4: This is magnesium sulfate, another ionic compound. It forms when magnesium reacts with sulfate ions (SO4^2-). It consists of one magnesium ion (Mg^2+) and one sulfate ion (SO4^2-).

It's important to note that while all of these compounds contain magnesium (Mg), they have different chemical compositions and properties.
