Answer 2

Reaction 1: Mg + 2HCl = MgCl + H2↑

The reaction between magnesium (Mg) and hydrochloric acid (HCl) produces magnesium chloride (MgCl) and hydrogen gas (H2) as a product. This is a single displacement reaction where magnesium replaces hydrogen in hydrochloric acid to form magnesium chloride. The balanced chemical equation for this reaction is:

Mg + 2HCl = MgCl + H2↑

Reaction 2: MgCl2 + 2NaOH = Mg(OH)2↓ + 2NaCl

The reaction between magnesium chloride (MgCl2) and sodium hydroxide (NaOH) produces magnesium hydroxide (Mg(OH)2) and sodium chloride (NaCl) as products. This is a double displacement reaction where the positive ions of one compound switch places with the positive ions of the other compound. The balanced chemical equation for this reaction is:

MgCl2 + 2NaOH = Mg(OH)2↓ + 2NaCl

Reaction 3: Mg(OH)2 = MgO + H2O

The reaction between magnesium hydroxide (Mg(OH)2) results in the formation of magnesium oxide (MgO) and water (H2O). This is a decomposition reaction where a compound breaks down into simpler substances. The balanced chemical equation for this reaction is:

Mg(OH)2 = MgO + H2O

Reaction 4: MgO + SO3 = MgSO4

The reaction between magnesium oxide (MgO) and sulfur trioxide (SO3) produces magnesium sulfate (MgSO4). This is a combination reaction where two or more substances combine to form a new compound. The balanced chemical equation for this reaction is:

MgO + SO3 = MgSO4

Reaction 5: MgSO4 + Ba(NO3)2 = BaSO4 + Mg(NO3)2

The reaction between magnesium sulfate (MgSO4) and barium nitrate (Ba(NO3)2) produces barium sulfate (BaSO4) and magnesium nitrate (Mg(NO3)2). This is also a double displacement reaction where the positive ions of one compound switch places with the positive ions of the other compound. The balanced chemical equation for this reaction is:

MgSO4 + Ba(NO3)2 = BaSO4 + Mg(NO3)2 I hope this helps! Let me know if you have any further questions.
