Question

K+H2SO4 = Cu+H2SO4 = Ag+H2SO4 = Na2O+H2SO4 = CO2+H2SO4 = Ba(OH)2+H2SO4 = NaOH+H2SO4 = HCL+H2SO4 = K2S+H2SO4 = Na2SO3+H2SO4 =

Answer 1

2K + H2So4= K2So4+ H2
Cu+ 2H2So4= SO2+ 2H2O+ CuSo4
2Ag+ H2SO4= Ag2SO4 + So2+2h2o
Na2o + H2SO4=Na2So4+h2o
Co2+ H2so4= So3+ H2co3
Ba(oh)2+ h2so4= Baso4+2h2o
2naoh+h2so4= Na2so4+2h2o
Hcl+h2so4= Hso3Cl+ h2o
k2s+h2so4= K2So4+ H2s
Na2so3+ h2so4= Na2So4+so2+h20

Answer 2

To balance the chemical equations you provided, we need to make sure that the number of atoms of each element is the same on both sides of the equation. I'll balance each equation one by one:

1. K + H2SO4 → K2SO4 + H2 (2K + H2SO4 → K2SO4 + H2)

2. Cu + H2SO4 → CuSO4 + H2 (Cu + H2SO4 → CuSO4 + H2)

3. Ag + H2SO4 → Ag2SO4 + H2 (2Ag + H2SO4 → Ag2SO4 + H2)

4. Na2O + H2SO4 → Na2SO4 + H2O (Na2O + H2SO4 → Na2SO4 + H2O)

5. CO2 + H2SO4 → CO2(SO4) + H2O (CO2 + H2SO4 → CO2(SO4) + H2O)

6. Ba(OH)2 + H2SO4 → BaSO4 + 2H2O (Ba(OH)2 + H2SO4 → BaSO4 + 2H2O)

7. NaOH + H2SO4 → Na2SO4 + 2H2O (2NaOH + H2SO4 → Na2SO4 + 2H2O)

8. HCl + H2SO4 → HClSO4 + H2O (HCl + H2SO4 → HClSO4 + H2O)

9. K2S + H2SO4 → K2SO4 + H2S (K2S + H2SO4 → K2SO4 + H2S)

10. Na2SO3 + H2SO4 → Na2SO4 + H2O + SO2 (Na2SO3 + H2SO4 → Na2SO4 + H2O + SO2)

Note: The balanced chemical equations above show the correct stoichiometric coefficients for each reactant and product to satisfy the law of conservation of mass.
