3. Химическую реакцию, уравнение которой
$2Al + 6HCl = 2AlCl_3 + 3H_2\uparrow,$

1) соединения
2) разложения
3) обмена
4) замещения
Решение. №3 (с. 167)
Решение 2. №3 (с. 167)
Для определения типа химической реакции, представленной уравнением $2\text{Al} + 6\text{HCl} = 2\text{AlCl}_3 + 3\text{H}_2\uparrow$, необходимо проанализировать состав реагентов и продуктов.
В левой части уравнения находятся реагенты:
1. Алюминий ($\text{Al}$) — простое вещество.
2. Соляная кислота ($\text{HCl}$) — сложное вещество.
В правой части уравнения находятся продукты:
1. Хлорид алюминия ($\text{AlCl}_3$) — новое сложное вещество.
2. Водород ($\text{H}_2$) — новое простое вещество.
Мы видим, что атомы простого вещества (алюминия) заместили атомы одного из элементов (водорода) в сложном веществе (соляной кислоте). Такой тип химического взаимодействия, при котором атомы простого вещества замещают атомы одного из элементов в сложном веществе, называется реакцией замещения.
Данная реакция не относится к другим типам:
• Реакция соединения предполагает образование одного сложного продукта из нескольких простых или сложных.
• Реакция разложения — это распад одного сложного вещества на несколько более простых.
• Реакция обмена происходит между двумя сложными веществами, которые обмениваются своими составными частями.
Следовательно, данная реакция является реакцией замещения.
Ответ: 4) замещения.
