Цифры, стоящие ПЕРЕД каким-либо веществом в уравнении реакции показывает, какое количество этого вещества вствпило в реакцию. Маленькие цифры, стоящие после элементов снизу - это индексы, они показывают количество атомов в молекуле, т. е. отвечают за количественный и качественный состав. K2MnO4 - это перманганат калия, в котором содержится 2 атома калия, а вот KMnO4 - это манганат калия, совсем другое вещество, содержащий один атом калия. Мы видим, что индексы играют просто огромнейшую роль при составлении молекулярных формул веществ.
