Question

Установи соответствие между формулой вещества и его характеристикой. 1 — SO2, 2 — SO3, 3 — H2S, 4 — H2SO4; а — образуется при каталитическом окислении сернистого газа; б — бесцветный газ с запахом тухлых яиц; в — смешивается с водой в любых соотношениях; г — используется для обеззараживания помещений; д — не растворяется в воде. Помогите пожалуйста срочно

Answer 1

Ответ:

1. Г

2. А

3. Б

4. В

Объяснение:

1. Сернистый газ SO₂ используют для обеззараживания помещений

2. SO₃ образуется при каталитическом окислении SO₂

3. H₂S - бесцветный газ с запахом тухлых яиц

4. H₂SO₄ - смешивается с водой в любых отношениях

Answer 2

I can help you with this question. Here is a detailed answer:

The formula of a substance and its characteristic are matched as follows:

- 1 - SO2: This is sulfur dioxide, a colorless gas that is formed by the catalytic oxidation of sulfur dioxide gas. It can be used for disinfecting rooms, as it has a strong bactericidal effect. It also reacts with water to form sulfurous acid, a weak acid that can act as both an oxidizing and a reducing agent in reactions. The answer is a and g. - 2 - SO3: This is sulfur trioxide, a white solid that is formed by the further oxidation of sulfur dioxide. It does not dissolve in water, but reacts violently with it to form sulfuric acid, a strong acid that is widely used in industry and laboratory. The answer is d. - 3 - H2S: This is hydrogen sulfide, a colorless gas that has a rotten egg smell. It is formed by the decay of organic matter containing sulfur, such as proteins. It is a weak acid that reacts with bases to form salts. It also dissolves in water in any proportions, forming a solution that can be tested with lead acetate paper for the presence of sulfide ions. The answer is b and v. - 4 - H2SO4: This is sulfuric acid, a colorless liquid that is formed by the reaction of sulfur trioxide and water. It is a strong acid that reacts with metals, bases, and salts to form various products. It also mixes with water in any proportions, forming a solution that can be concentrated by distillation. The answer is v.

I hope this helps you understand the question better.
