Question

В ходе реакции некоторого металла с соляной кислотой выделился бесцветный газ. Определите, какой это газ?

Answer 1

В ходе реакции некоторого металла с соляной кислотой выделился бесцветный газ - H2 - водород.

Answer 2

Ответ:

В ходе реакции выделится соль и водород (H2)

Пример: Mg + 2HCl → MgCl2 + H2 ↑, при взаимодействии магния с соляной кислотой образуется хлорид магния и выделяется водород.

Identification of the Gas Produced in the Reaction of a Metal with Hydrochloric Acid

In the reaction between a metal and hydrochloric acid, a colorless gas is produced. To determine the identity of this gas, we need to consider the reaction between metals and hydrochloric acid.

When a metal reacts with hydrochloric acid, the metal displaces hydrogen from the acid, resulting in the formation of a metal chloride and the release of hydrogen gas. The metal chloride is typically soluble in water and remains in solution.

The general equation for the reaction between a metal and hydrochloric acid is:

Metal + Hydrochloric Acid → Metal Chloride + Hydrogen Gas

Now, let's consider some possible metals that could react with hydrochloric acid and produce a colorless gas:

1. Zinc (Zn): Zinc reacts with hydrochloric acid to produce zinc chloride and hydrogen gas. The reaction can be represented by the following equation:

Zn + 2HCl → ZnCl2 + H2

2. Aluminum (Al): Aluminum reacts with hydrochloric acid to produce aluminum chloride and hydrogen gas. The reaction can be represented by the following equation:

2Al + 6HCl → 2AlCl3 + 3H2

3. Magnesium (Mg): Magnesium reacts with hydrochloric acid to produce magnesium chloride and hydrogen gas. The reaction can be represented by the following equation:

Mg + 2HCl → MgCl2 + H2

Based on these reactions, it is likely that the colorless gas produced in the reaction of a metal with hydrochloric acid is hydrogen gas (H2).

Please note that the specific metal used in the reaction and the concentration of the hydrochloric acid can affect the reaction rate and the amount of gas produced. Additionally, other factors such as temperature and pressure can also influence the reaction.
