Question

Mg+HNO3= Zn+H3PO4= Mg(OH)2+H2SO4= BaCl2+H2SO3= H2CO3+NaOH= H2CO3=

Answer 1

Ответ:

Mg + 4 HNO3 → Mg(NO3)2 + 2 NO2 + 2 H2O

3 Zn + 2 H3PO4 → Zn3(PO4)2 + 3 H2

H2SO4 + Mg(OH)2 → 2 H2O + MgSO4

BaCl2 + Na2SO4 → BaSO4 + 2 NaCl

H2CO3 + 2 NaOH → Na2CO3 + 2 H2O

H2CO3 → H2O + CO2

Answer 2

Let's go through each of the chemical reactions you've mentioned:

1. Mg + HNO3: This is a single replacement reaction where magnesium (Mg) reacts with nitric acid (HNO3). The balanced equation is:

   Mg + 2HNO3 → Mg(NO3)2 + H2

2. Zn + H3PO4: This is also a single replacement reaction where zinc (Zn) reacts with phosphoric acid (H3PO4). The balanced equation is:

   Zn + 2H3PO4 → Zn(H2PO4)2 + H2

3. Mg(OH)2 + H2SO4: This is a double replacement reaction where magnesium hydroxide (Mg(OH)2) reacts with sulfuric acid (H2SO4). The balanced equation is:

   Mg(OH)2 + H2SO4 → MgSO4 + 2H2O

4. BaCl2 + H2SO3: This is also a double replacement reaction where barium chloride (BaCl2) reacts with sulfurous acid (H2SO3). The balanced equation is:

   BaCl2 + H2SO3 → BaSO3 + 2HCl

5. H2CO3 + NaOH: This is a neutralization reaction where carbonic acid (H2CO3) reacts with sodium hydroxide (NaOH). The balanced equation is:

   H2CO3 + 2NaOH → Na2CO3 + 2H2O

6. H2CO3: Carbonic acid (H2CO3) is a weak acid and tends to exist in equilibrium with its dissociation products. The balanced equation for the dissociation of carbonic acid is:

   H2CO3 ⇌ H2O + CO2

Please note that the reactions involving carbonic acid (H2CO3) are typically reversible reactions, and the equilibrium lies towards the products in an aqueous environment.
