Question

Поможіть срочно будьласка Здійснити перетворення: S→SO2→H2SO3. 1) Вкажіть формулу сполуки, яку необхідно додати до сульфуру, щоб утворився сульфур (ІV)оксид. 2) Позначте тип реакції під час, якої утворилася сульфітна кислота.

Answer 1

Ответ:

1)S→SO2→H2SO3

S+O2=SO2

SO2+H2O=H2SO3

Щоб утворився сульфур (IV) оксид , потрібно до сульфуру додати кисень, тобто О2.

2)SO2+H2O=H2SO3( це реакція сполучення, коли з двох речовин утворюється одна).

Answer 2

Transformation: S → SO2 → H2SO3

To understand the transformation of sulfur (S) into sulfur (IV) oxide (SO2) and then into sulfurous acid (H2SO3), let's break it down step by step.

1) Formula for the compound needed to form sulfur (IV) oxide:

To form sulfur (IV) oxide (SO2), we need to add a compound containing oxygen to sulfur. The compound that can be added to sulfur to form SO2 is oxygen itself (O2). When sulfur reacts with oxygen, it undergoes oxidation and forms sulfur (IV) oxide.

The balanced equation for the reaction is:

S + O2 → SO2

In this reaction, sulfur gains oxygen and is oxidized to form sulfur (IV) oxide.

2) Type of reaction that forms sulfurous acid:

The formation of sulfurous acid (H2SO3) involves the reaction of sulfur (IV) oxide with water (H2O). This reaction is known as a neutralization reaction or an acid-base reaction.

The balanced equation for the reaction is:

SO2 + H2O → H2SO3

In this reaction, sulfur (IV) oxide reacts with water to form sulfurous acid. The sulfur (IV) oxide acts as an acid, while water acts as a base. The reaction between an acid and a base results in the formation of a salt and water.

So, the type of reaction that forms sulfurous acid is an acid-base reaction or a neutralization reaction.
