Question

MgCO3-MgCl-Mg-MgSO4-(MgNO3)2

Answer 1

MgCO3 + 2HCl = MgCl2 + H2O + CO2

MgCl2 + Ba = BaCl2 + Mg

Mg + H2SO4(p)= MgSO4 + H2

MgSO4 + Ba(NO3)2 = BaSO4 + Mg(NO3)2

Answer 2

The chemical sequence you provided seems to represent the formation of magnesium compounds through a series of reactions. Let's break it down step by step:

1. MgCO3: Magnesium carbonate (MgCO3) is a white, crystalline solid that can be formed by the reaction between magnesium ions (Mg2+) and carbonate ions (CO32-). It is commonly found in minerals like magnesite.

2. MgCl: The notation "MgCl" is incomplete, as it does not specify the accompanying anion. However, if we assume it refers to magnesium chloride (MgCl2), it is a white crystalline solid that consists of one magnesium ion (Mg2+) and two chloride ions (Cl-).

3. Mg: The notation "Mg" likely represents elemental magnesium, which is a metallic element with the symbol Mg. It is a lightweight, silver-white metal commonly found in various minerals.

4. MgSO4: Magnesium sulfate (MgSO4) is a white crystalline solid composed of one magnesium ion (Mg2+) and one sulfate ion (SO42-). It can be produced through the reaction between magnesium hydroxide (Mg(OH)2) and sulfuric acid (H2SO4).

5. (MgNO3)2: This notation represents magnesium nitrate (Mg(NO3)2), a white crystalline solid consisting of one magnesium ion (Mg2+) and two nitrate ions (NO3-). It can be obtained by reacting magnesium oxide (MgO) or magnesium hydroxide (Mg(OH)2) with nitric acid (HNO3).

Overall, the sequence appears to represent a progression of reactions involving magnesium and different anions, leading to the formation of various magnesium compounds.
