Степень окисления азота +3. </li><li> $NO_2$ — оксид азота(IV), или диоксид азота. Степень окисления азота +4. </li><li> $N_2O_4$ — оксид азота(IV), или тетраоксид диазота (является димером $NO_2$). Степень окисления азота +4. </li><li> $N_2O_5$ — оксид азота(V), или пентаоксид диазота. Степень окисления азота +5. </li></ul><p>Другими примерами могут служить:</p><ul><li>Углерод (C) и кислород (O): оксид углерода(II) - $CO$ и оксид углерода(IV) - $CO_2$.</li><li>Сера (S) и кислород (O): оксид серы(IV) - $SO_2$ и оксид серы(VI) - $SO_3$.</li><li>Железо (Fe) и кислород (O): оксид железа(II) - $FeO$, оксид железа(III) - $Fe_2O_3$ и смешанный оксид - $Fe_3O_4$.</li></ul><p><strong>Ответ:</strong> Примером двух элементов, образующих несколько соединений, являются азот (N) и кислород (O). Формулы их соединений (оксидов): $N_2O$, $NO$, $N_2O_3$, $NO_2$, $N_2O_5$.</p>" ] #changes: [] #casts: [] #classCastCache: [] #attributeCastCache: [] #dateFormat: null #appends: [] #dispatchesEvents:

3. Два элемента могут образовать между собой несколько разных со-единений и в неорганической химии. Приведите пример таких эле-ментов, напишите формулы соединений.
Решение. №3 (с. 10)
Решение 2. №3 (с. 10)
Способность двух элементов образовывать несколько различных соединений друг с другом объясняется тем, что один или оба элемента могут проявлять переменные степени окисления. Это явление особенно характерно для неметаллов, а также для многих переходных металлов. Закон, описывающий такие соотношения, называется законом кратных отношений.
Решение
В качестве примера можно рассмотреть пару элементов: азот (N) и кислород (O). Азот, как элемент V группы, может проявлять различные положительные степени окисления в соединениях с более электроотрицательным кислородом. Это приводит к образованию целого ряда оксидов азота.
Вот список основных соединений, образуемых азотом и кислородом:
- $N_2O$ — оксид азота(I), или закись азота. В этом соединении степень окисления азота +1.
- $NO$ — оксид азота(II), или монооксид азота. Степень окисления азота +2.
- $N_2O_3$ — оксид азота(III), или триоксид диазота. Степень окисления азота +3.
- $NO_2$ — оксид азота(IV), или диоксид азота. Степень окисления азота +4.
- $N_2O_4$ — оксид азота(IV), или тетраоксид диазота (является димером $NO_2$). Степень окисления азота +4.
- $N_2O_5$ — оксид азота(V), или пентаоксид диазота. Степень окисления азота +5.
Другими примерами могут служить:
- Углерод (C) и кислород (O): оксид углерода(II) - $CO$ и оксид углерода(IV) - $CO_2$.
- Сера (S) и кислород (O): оксид серы(IV) - $SO_2$ и оксид серы(VI) - $SO_3$.
- Железо (Fe) и кислород (O): оксид железа(II) - $FeO$, оксид железа(III) - $Fe_2O_3$ и смешанный оксид - $Fe_3O_4$.
Ответ: Примером двух элементов, образующих несколько соединений, являются азот (N) и кислород (O). Формулы их соединений (оксидов): $N_2O$, $NO$, $N_2O_3$, $NO_2$, $N_2O_5$.
