Расставьте коэффициенты в уравнениях хим. реакций (обратите внимание, что коэффициент одновременно изменяет число атомов двух или нескольких элементов)

HCl + O2 -> Cl2 + H2O

Fe2O3 + HCl -> FeCl3 + H2O

Al4C3 + HCl -> AlCl3 + CH4

Fe + H2O -> Fe2O3 + H2

N2 + H2 -> NH3

4HCl+O2=2Cl2+2H2O
Fe2O3+6HCl=2FeCl3+3H2O
Al4C3+12HCl=4AlCl3+3CH4
2Fe+3H2O=Fe2O3+3H2
N2+3H2=2NH3
