Fe⁺²O + HN⁺⁵O₃⇒ Fe⁺³(NO₃)₃ + N⁺⁴O₂ + H₂O

Fe⁺²-1e⁻ Fe⁺³ 1восстановитель, процесс окисления
N⁺⁵+ 1e⁻ N⁺⁴ 1 окислитель, процесс восстановления

2FeO + 8HNO₃= 2Fe(NO₃)₃ + 2NO₂ + 4H₂O

Для расстановки коэффициентов выбран алгебраический метод (в уравнении левая часть должна равняться правой части).

Parodox22: все коэффициенты можно разделить на 2, и всё тоже уровняется!!!

Parodox22: FeO+4HNO3->NO2+Fe(NO3)3+2H2O

Срочноооооо! Напишите краткое содержание
All children, except one, grow up. They just know that they will grow up, and in the way Wendy knew was this. One day when she was two years old she was playing in the garden, and she plucked another flower and ran with it to her mother. I suppose she must have looked rather delightful, for Mrs. Darling put her hand to her heart and cried, "Oh, why can't you remain like this for ever!" That was all that passed between them on this subject, but henceforth Wendy knew she must grow up. You always know after You are two. Two is at the beginning of the end.

Of course they lived at 14 [their house number on their street], and until Wendy came her mother was the chief one. She was a very sweet lady, with a romantic mind and such a sweet mocking mouth. Her romantic mind was like the tiny boxes, one in another, that come from the puzzling East, however many you discover there is always one more; and her sweet mocking mouth had one kiss on it that Wendy could never know, although there it was, perfectly conspicuous in the right corner.

In the direction of the Lord. Darling won her was this: the many gentlemen who were already boys , when she was a girl discovered simultaneously that they loved her, and they all ran to her house to suggest that she in addition to Mr. Darling, who took a cab and nipped in first, and so he got it. He took everything from her, except the innermost box and the kiss. He never knew about this box, and in time he gave up trying for the kiss. Wendy thought Napoleon could have got it but I can picture him trying, and then it will be Off in a passion, slamming the door.е краткое содержание
