Решение
Спектральный анализ — это метод определения химического состава вещества по его спектру. Каждый химический элемент имеет свой уникальный линейчатый спектр (в данном случае — спектр поглощения), который можно считать его «отпечатком». Спектр поглощения смеси газов представляет собой наложение спектров всех газов, входящих в ее состав. Это означает, что в спектре смеси будут присутствовать все линии поглощения, характерные для каждого из ее компонентов.
Чтобы определить состав неизвестного газа, сравним его спектр поглощения («Газ») со спектрами водорода («H») и гелия («He»).
Сначала сравним спектр неизвестного газа со спектром водорода (H). Мы видим, что все темные линии, присутствующие в спектре водорода, точно совпадают с некоторыми линиями в спектре неизвестного газа. Это говорит о том, что в состав газа входит водород.
Теперь сравним спектр неизвестного газа со спектром гелия (He). Все линии поглощения, характерные для гелия, также присутствуют в спектре неизвестного газа на тех же местах. Это означает, что в составе газа также есть гелий.
Наконец, проверим, есть ли в спектре неизвестного газа линии, которые не принадлежат ни водороду, ни гелию. Внимательно изучив спектр газа, можно увидеть, что каждая его линия поглощения соответствует либо линии из спектра водорода, либо линии из спектра гелия. Никаких дополнительных, «посторонних» линий нет.
Таким образом, неизвестный газ является смесью, состоящей только из атомов гелия и водорода. Этому выводу соответствует вариант ответа №3.
Ответ: 3) только атомы гелия и водорода.
