Question

Расставьте коэффициенты: Li2C3 + H2O = LiOH + C2H2 NH3 +H2SO4 = NH4HSO4 N2O5 = NO2 + O2 FeO = NH3 = Fe + N2 + H2O

Answer 1

Li2C2 + 2H2O = 2LiOH + C2H2
NH3 +H2SO4 = NH4HSO4
2N2O5 = 4NO2 + O2
3FeO+  2NH3 = 3Fe + N2 + 3H2O

Answer 2

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 balance the given chemical equations.

1. Li2C3 + H2O = LiOH + C2H2 - The balanced equation is: ``` Li2C3 + 3H2O = 2LiOH + C2H2 ```

2. NH3 + H2SO4 = (NH4)HSO4 - The balanced equation is: ``` NH3 + H2SO4 = (NH4)HSO4 ```

3. N2O5 = NO2 + O2 - The balanced equation is: ``` 2N2O5 = 4NO2 + O2 ```

4. FeO + NH3 = Fe + N2 + H2O - The balanced equation is: ``` 4FeO + 6NH3 = 4Fe + 3N2 + 6H2O ```

Conclusion

The chemical equations have been balanced according to the law of conservation of mass. If you have any more questions or need further assistance, feel free to ask!
