Question

KOH+FeSO4= CuCl2+H2S= CaCO3+HCL= AgNO3+BaBr2= H2S+Pb(No3)2= NaOH+HNO3= BaCO3+HCL=

Answer 1

Ответ:

1. 2KOH+FeSO4=Fe(OH)2 (стрелка вниз-осадок) +K2SO4

2. CuCL2+H2S=CuS(в осадок) + 2HCL

3. CaCO3+2HCL=CaCL2+H2O+CO2(стрелка вверх)

4. 2AgNo3+BaBr2=2AgBr(стрелка вниз)+Ba(No3)2

5. H2S+Pb(No3)2=2HNO3+PbS(стрелка вниз)

6. NaOH+HNO3=NANO3+H2O

7. BaCO3+2HCL=BaCL2+H2O+CO2(стрелка вверх)

Answer 2

It seems like you've provided a list of chemical reactions and their reactants. I can help you balance these chemical equations and provide you with the balanced equations:

1. KOH + FeSO4 → K2SO4 + Fe(OH)2

2. CuCl2 + H2S → CuS + 2HCl

3. CaCO3 + 2HCl → CaCl2 + CO2 + H2O

4. 2AgNO3 + BaBr2 → 2AgBr + Ba(NO3)2

5. H2S + Pb(NO3)2 → PbS + 2HNO3

6. 2NaOH + HNO3 → NaNO3 + 2H2O

7. BaCO3 + 2HCl → BaCl2 + CO2 + H2O

Please note that these balanced equations represent the chemical reactions you provided. If you have any specific questions or if you need further assistance, feel free to ask!
