Question

Помогите пожалуйста. Решите и объясните как это решать. FeO+CO--Fe+CO2 Fe3O4+CO--CO2+Fe FeO3+CO--Fe+Co2 Na+H2O--NaOH+H2 Na+NH3--NaNH2+H2 H2O+K--H2+KOH CaO+H2O--CA(OH) FE+H2O--FE3O4+H2 H2O2--H2O+O2 CU(NO3)2--CUO+NO2

Answer 1

Первое уравнивать не нужно, там и так все поровну.
Fe3O4+4CO->3Fe+4CO2
Fe2О3+ 3CO->2Fe+3CO2
2Na+2H2O->2NaOH+H2
2Na+2NH3->2NaNH2+H2(впервые такое вижу)
2К+2H2O->2KOH+H2
СаО+Н2О->Са(ОН)2(это точно, у вас много ошибок)
3Fe+4H2O->Fe3O4+4H2
2H2O2->2H2O+O2
2Cu(NO3)2->2CuO+4NO2+O2 это тоже только так, иначе ошибка.Удачи.

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the same number of each type of atom is present on both sides of the equation. Let's start by balancing the given chemical equations one by one.

1. FeO + CO → Fe + CO2 To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides. The balanced equation is: ``` FeO + CO → Fe + CO2 ```

2. Fe3O4 + CO → CO2 + Fe

The balanced equation for this reaction is: ``` Fe3O4 + 4CO → 3Fe + 4CO2 ```

3. Na + H2O → NaOH + H2

The balanced equation for this reaction is: ``` 2Na + 2H2O → 2NaOH + H2 ```

4. Na + NH3 → NaNH2 + H2

The balanced equation for this reaction is:
