Question

complete the following reaction
1. koh + CO2
2.ca(oh)2 + SO2
3.HCL + H2 so4
4.H2so4 + znso4​

Answer 1

Answer:

1. koh+co2=2KOH + CO2 → K2CO3 + H2O
2. 2KOH + CO2 → K2CO3 + H2OPotassium hydroxide react with carbon dioxide to produce potassium carbonate and water. Potassium hydroxide - concentrated solution
3. ca(oh)2+so2=Ca(OH)2 + SO2. CaSO3 + H2O
4. Ca(OH)2 + SO2. CaSO3 + H2OCalcium hydroxide react with sulfur dioxide to produce calcium sulfite and water. The reaction takes place in aboiling solution.
5. Hcl+H2so4=HCl + H2SO4 → HSO3Cl +H2O
6. H2so4+znso4=ZnSO4+H2
