Answer 1

Ответ:

Объяснение:

Al в ряде активности мене активный чем Mg ,поэтому в 4 берем Al(OH)3

Answer 2

The chemical equation you provided seems to indicate that all the compounds listed have the same amount of magnesium (Mg). However, there appears to be a mistake in the equation. The chemical formulas are not balanced, and they don't represent a chemical reaction.

To clarify, Mg is the chemical symbol for magnesium, and the compounds you mentioned are as follows:

1. Mg: Elemental magnesium (Mg).
2. MgO: Magnesium oxide, a compound formed by the combination of magnesium and oxygen.
3. MgCl2: Magnesium chloride, a compound formed by the combination of magnesium and chlorine.
4. Mg(OH)2: Magnesium hydroxide, a compound formed by the combination of magnesium, oxygen, and hydrogen.
5. MgS: Magnesium sulfide, a compound formed by the combination of magnesium and sulfur.

To represent a balanced chemical reaction, you would need a starting compound or a reaction between these compounds. For example:

Mg + 2HCl → MgCl2 + H2

This represents the reaction of magnesium (Mg) with hydrochloric acid (HCl) to produce magnesium chloride (MgCl2) and hydrogen gas (H2).
