Question

H2SO4+K2SiO3 H2SO4+NaOH H2SO4+BaCE2 K2SiO3+BaCE2 K2SiO3+BaCE2

Answer 1

H2SO4 + K2SiO3 = K2SO4 + H2SiO3

H2SO4 + NaOH = NaHSO4 + H2O

H2SO4 + BaCl2 = BaSO4 + 2HCl

K2SiO3 + BaCl2 = BaSiO3 + 2KCl

_______

CE??

Answer 2

It appears that you have provided a list of chemical reactions, but some of them seem to be repeated. I'll write down the balanced chemical equations for the unique reactions:

1. H2SO4 + K2SiO3 → K2SO4 + H2SiO3
2. H2SO4 + NaOH → Na2SO4 + H2O
3. H2SO4 + BaCE2 → BaSO4 + H2CE2
4. K2SiO3 + BaCE2 → BaSiO3 + K2CE2

Please note that I have used "CE2" as a placeholder since the exact chemical formula is not specified. If you provide the correct chemical formula for "CE2," I can adjust the equations accordingly. Also, double-check the reactions you've given to ensure there are no duplicate entries. If you meant to provide different reactions, please let me know, and I'll be happy to help!
