Ответ:1)Согласно по этой реакции

168г ---------------- х=240г

4Fe + 3O2 => 2Fe2O3

224г ---------------- 320г

Ответ: При взаимодействии 160 г железа с кислородом образуется 240г оксида железа трехвалетного

2) 168г-------x=50.4л

4Fe + 3O2 => 2Fe2O3

224г------67.2л

Ответ: При взаимодействии 160 г железа потребуется 50.4л кислорода с образованием оксида железа трехвалентного

Объяснение:Взаимодействие железа и кислорода с образованием оксида железа трехвалетного:

4Fe+3O2=>2Fe2O3
