Question

Сравните реакции соединения и разложения (разложения и замещения, замещения и соединения): а) по числу взятых и полученных веществ; б) по тому, являются ли исходные и полученные вещества простыми или сложными.

Answer 1

1) Реакции соединения и разложения:
соединение: простое + простое = сложное
разложение: сложное = простое + простое
2) Реакции разложения и замещения:
разложение: сложное = простое + простое
замещения: сложное + простое = сложное + простое
3) Реакции замещения и соединения:
замещения: сложное + простое = сложное + простое
соединение: простое + простое = сложное

Answer 2

Comparing Reactions of Combination and Decomposition

When comparing the reactions of combination and decomposition, several factors can be considered:

a) Number of Substances Involved

Combination Reactions: In a combination reaction, two or more substances combine to form a single substance. Decomposition Reactions: In a decomposition reaction, a single compound breaks down into two or more simpler substances.

The number of substances involved in the reactions differs: - In combination reactions, multiple substances combine to form a single substance. - In decomposition reactions, a single compound breaks down into multiple substances.

b) Nature of Substances Involved

Combination Reactions: The substances involved in a combination reaction can be simple or compound. Decomposition Reactions: The substances involved in a decomposition reaction are typically compounds that break down into simpler substances.

The nature of the substances involved in the reactions can be categorized as: - In combination reactions, the initial substances can be simple or compound. - In decomposition reactions, the initial substance is typically a compound that breaks down into simpler substances.

In summary, combination reactions involve the combination of multiple substances to form a single substance, while decomposition reactions involve the breakdown of a single compound into multiple substances.
