Question

решите пожалуйста, люди добрые и умные) SO2 + Х = H2SO3 SO2 + X = Na2SO3 + ... H2SO4 + X = Na2SO4 H2SO4 + X = NaHSO4 H2SO4 + X = Cu(OH)2 H2SO4 + X = BaCL2 SO3 + X = ZnSO4 SO3 + X = CaSO4

Answer 1

1) SO2 + H2O = H2SO3

2) SO2 + 2NaOH = Na2SO3 + H2O

3) H2SO4 + NaOH = Na2SO4 + H2O

4) H2SO4 + Na2SO4 = 2NaHSO4

5) CuSO4 + 2NaOH = Na2SO4 + Cu(OH)2(осадок,стрелка вниз)

6) BaSO4 + CaCl2 = CaSO4 + BaCl2

7) SO3 + ZnO = ZnSO4

8) SO3 + CaO = CaCO3(осадок,стрелка вниз)

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the same number of each type of atom is present on both sides of the equation. Let's balance the given chemical equations step by step.

1. Balancing the Equation: SO2 + X = H2SO3 - The balanced equation is: SO2 + H2O = H2SO3.

2. Balancing the Equation: SO2 + X = Na2SO3 - The balanced equation is: SO2 + 2NaOH = Na2SO3 + H2O.

3. Balancing the Equation: H2SO4 + X = Na2SO4 - The balanced equation is: H2SO4 + 2NaOH = Na2SO4 + 2H2O.

4. Balancing the Equation: H2SO4 + X = NaHSO4 - The balanced equation is: H2SO4 + NaOH = NaHSO4 + H2O.

5. Balancing the Equation: H2SO4 + X = Cu(OH)2 - The balanced equation is: H2SO4 + Cu(OH)2 = CuSO4 + 2H2O.

6. Balancing the Equation: H2SO4 + X = BaCl2 - The balanced equation is: H2SO4 + BaCl2 = BaSO4 + 2HCl.

7. Balancing the Equation: SO3 + X = ZnSO4 - The balanced equation is: SO3 + H2O = H2SO4 and H2SO4 + ZnO = ZnSO4 + H2O.

8. Balancing the Equation: SO3 + X = CaSO4 - The balanced equation is: SO3 + Ca(OH)2 = CaSO4 + H2O.
