Написать уровнения реакции по схеме , для реакции 1 составить электронный баланс для реакции 4 ионное уравненние. 1)С-- СH4 - CO2 - CaCO3 - CaCl2 - CaCO3 Написать уровнения реакции по схеме , для реакции 1 составить электронный баланс для реакции 5 ионное уравненние. 1)S - FeS - SO2 - SO3 - H2SO4 - BaSO4 2)N2 - Li3N - NO - NO2 - HNO3 - Cu(NO3)2

Answer 1

С+2Н2=СН4
СН4+2О2=СО2+2Н2О
СО2+СаО=СаСО3
СаСО3+2НСl=СаСl2+Н2О+СО2
СаСl2+Н2О+СО2=СаСО3+2НСl

Answer 2

Writing Chemical Equations for Reactions 1 and 4

The chemical equations for reactions 1 and 4 are as follows:

1) Reaction 1: - Balanced Equation: ``` CaCO3 + 2HCl → CaCl2 + CO2 + H2O ``` - Electron Balance: Not applicable for this reaction. - Ion Equation: ``` CaCO3(s) + 2H+(aq) + 2Cl-(aq) → Ca2+(aq) + 2Cl-(aq) + CO2(g) + H2O(l) ```

4) Reaction 4: - Balanced Equation: ``` S + FeS + 2HCl → SO2 + FeCl2 + H2S ``` - Electron Balance: Not applicable for this reaction. - Ion Equation: ``` S(s) + Fe2+(aq) + 2Cl-(aq) + 2H+(aq) → SO2(g) + Fe2+(aq) + 2Cl-(aq) + H2S(g) ```

Writing Chemical Equations for Reactions 5 and 6

The chemical equations for reactions 5 and 6 are as follows:

5) Reaction 5: - Balanced Equation: ``` BaSO4 + H2SO4 → Ba(HSO4)2 ``` - Electron Balance: Not applicable for this reaction. - Ion Equation: ``` BaSO4(s) + H2SO4(aq) → Ba2+(aq) + 2HSO4-(aq) ```

6) Reaction 6: - Balanced Equation: ``` N2 + 3Li3N → 2Li3N + N2 ``` - Electron Balance: Not applicable for this reaction. - Ion Equation: ``` N2(g) + 3Li+(aq) + 3N3-(aq) → 2Li3N(s) + N2(g) ```

These equations represent the chemical reactions and their corresponding ion equations as per the given scheme.
