Question

Mg=MgCl2=Mg(OH)2=MgCl2

Answer 1

Ответ:

Объяснение:

Mg + 2HCl = MgCl2 + H2

MgCl2 + 2NaOH = Mg(OH)2↓ + 2NaCl

Mg(OH)2 + 2HCl = MgCl2 + 2H2O

Answer 2

It appears you are equating different chemical compounds involving magnesium (Mg), chlorine (Cl), and hydroxide ions (OH). Let's break down these equations:

1. Mg = Magnesium This equation simply represents the element magnesium (Mg) on its own.

2. MgCl2 = Magnesium Chloride This equation represents magnesium chloride, which is formed when magnesium (Mg) reacts with chlorine (Cl2) to produce MgCl2. Magnesium chloride is a compound often used in various applications, including as a de-icer, in medicine, and in the food industry.

3. Mg(OH)2 = Magnesium Hydroxide This equation represents magnesium hydroxide, which is formed when magnesium (Mg) reacts with hydroxide ions (OH-) to produce Mg(OH)2. Magnesium hydroxide is a white, insoluble compound often used as an antacid and laxative.

4. MgCl2 = Magnesium Chloride (Again) This is the same as equation 2, representing magnesium chloride.

In summary, you have listed different chemical compounds involving magnesium (Mg), chlorine (Cl), and hydroxide ions (OH). Each of these compounds has its own distinct chemical properties and uses.
