Proszę pomóżcie ! dobierzcie współczynniki liczbowe :
Ma to wyglądac tak :
2Al+3S-->Al (małe) 2 S i małe 3
4Al + 3C -> Al₄C₃
2Cu + O₂ -> 2CuO
3Pb + 2O₂ -> Pb₃O₄
N₂ + O₂ -> 2NO
N₂ + 2O₂ -> 2NO₂
2N₂O -> 2N₂ + O₂
2ClO₂ -> Cl₂ + 2O₂
4Al+3C-->Al4C3
2Cu+O2-->2CuO
3Pb+2O2-->Pb3O4
N2+O2-->2NO
N2+2O2-->2NO2
2N2O-->2N2+O2
2ClO2-->Cl2+2O2
