Answer 2

Identifying Carbon Dioxide Gas

To identify carbon dioxide gas, you can use a glowing splint. When carbon dioxide is passed through lime water, it turns milky due to the formation of calcium carbonate. This can be used as a test for the presence of carbon dioxide gas.

The correct answer to the given options is В) тлеющей лучинки. This is because a glowing splint is used to test for the presence of carbon dioxide gas. When the glowing splint is inserted into a container of carbon dioxide gas, it will be extinguished due to the lack of oxygen, indicating the presence of carbon dioxide.

This information is supported by the chemical reaction between carbon dioxide and lime water, which results in the formation of a white precipitate, indicating the presence of carbon dioxide
