Question

расставьте коэффициенты в уравнениях
1. CnH2n+2 + O2= CO2 + H2O
2. CnH2nO2 + O2= CO2 + H2O
3. CnH2n+2O2 + O2= CO2 + H2O
4. CnH2n+3N + O2= CO2 + H2O + N2
5. CnH2n+1Cl + O2= CO2 + H2O + HCl
6. CnH2nNCl + O2= CO2 + H2O + N2 + HCl

Answer 1

1. CnH2n+2 + (3n+1)/2O2= nCO2 + (n+1)H2O

2. CnH2nO2 + 3n/2O2= nCO2 + H2O

3. CnH2n+2O2 + (n+1.5)O2= nCO2 + nH2O

4. CnH2n+3N + (3n+1,5)O2= nCO2 + (n+1,5)H2O + 0,5N2  

5. CnH2n+1Cl + 1,5nO2= nCO2 + nH2O + HCl

6. CnH2nNCl + (3n-0.5)/2O2= nCO2 + (2n-1)/2H2O + N2 + HCl
