Надо расставить коофициенты 1. AgBr→Ag+Br2 2. Na+H2O→NaOH+H2 3. Fe(OH)2→FeO+H2O 4. NaOH+HCl→NaCl+H2O 5. CaO+H2O→Ca(OH)2 6. NO2+SO2→SO3+NO 7. NH3+Mg→Mg3N+H2 8. NH4NO3→N2+O2+H2O 9. NH4NO2→N2+H2O 10. P+HNO3→H3PO4+NO2+H2O 11. Fe2O3+CO→CO2+Fe 12. H2S+O2 →H2O+S 13. SiO2+Al→Al2O3+Si 14. H3P+O2→P2O5+H2O 15. KClO3+S→KCl+SO2 16. Fe(OH)3+HCl→FeCl3+H2O 17. FeCl3+NaOH→Fe(OH)3+NaCl

Answer 1

2agbr->2ag+br2

2na+2h2o->2naoh+h2

Fe(OH)2→FeO+H2O

NaOH+HCl→NaCl+H2O

CaO+H2O→Ca(OH)2

NO2+SO2→SO3+NO

2NH3+6Mg→2Mg3N+3H2

2NH4NO3→2N2+O2+4H2O

NH4NO2→N2+2H2O

P+5HNO3→H3PO4+5NO2+H2O

Fe2O3+3CO→3CO2+2Fe

2H2S+O2 →2H2O+2S

3SiO2+4Al→2Al2O3+3Si

2H3P+4O2→P2O5+3H2O

2KClO3+3S→2KCl+3SO2

Fe(OH)3+3HCl→FeCl3+3H2O

FeCl3+3NaOH→Fe(OH)3+3NaCl
