Question

ПОМОГИТЕ ПЛИЗЗЗЗЗ КАК МОЖНО СКОРЕЕ С ХИМИЕЙ Приведён ряд веществ: Na, S, O2, H2, Ag2O. Напиши уравнения реакций между веществами, в результате которых можно получить кислоты. В ответе укажи количество полученных кислот.

Answer 1

У меня получились только две кислоты:
1) H2+S=H2S
2) S+O2=SO2 - SO2+H2O=H2SO3

Answer 2

I can help you with your chemistry question. You have given a list of substances: Na, S, O2, H2, Ag2O. You want to write the equations of reactions between these substances, as a result of which you can obtain acids. You also want to indicate the number of acids obtained.

Here is my answer:

- To obtain acids, you need to react the substances with oxygen and water. For example, sulfur can react with oxygen to form sulfur dioxide, and then with water to form sulfurous acid:

S + O2 -> SO2 SO2 + H2O -> H2SO3

This is one acid obtained from sulfur.

- Similarly, silver oxide can react with water to form silver hydroxide, and then with carbon dioxide to form silver carbonate and carbonic acid:

Ag2O + H2O -> 2AgOH 2AgOH + CO2 -> Ag2CO3 + H2O CO2 + H2O -> H2CO3

This is another acid obtained from silver oxide.

- However, not all substances can form acids. For example, sodium is a metal that reacts with water to form sodium hydroxide and hydrogen gas:

Na + H2O -> NaOH + H2

Sodium hydroxide is a base, not an acid. Therefore, no acid can be obtained from sodium.

- Similarly, hydrogen is a non-metal that reacts with oxygen to form water:

H2 + O2 -> H2O

Water is a neutral substance, not an acid. Therefore, no acid can be obtained from hydrogen.

- In summary, from the list of substances given, you can obtain two acids: sulfurous acid and carbonic acid. The equations of the reactions are shown above. I hope this helps you with your chemistry homework.
