Question

How can you represent a liberation of gas in a reaction

Answer 1

Answer:

hydrogen

Explanation:

when you put matels above hydrogen in metal activity series they liberate hydrogen ions.

Answer 2

Answer:

Explanation:

• Hydrogen gas is released when acid interacts with metal. Along the metal's surface, gas bubbles have been seen to form. The bubbles are then placed in a soap solution, where the gas ignites and makes a popping sound when a candle is held close to it. Since only hydrogen gas makes a popping noise when it burns, it can be inferred that the substance is hydrogen

2H2​(g)+O2(g)→2H2O(g).

• When an acid interacts with a metal, hydrogen gas is released. To test it, place a burning candle close to the gas. For instance, when zinc metal reacts with dil, hydrogen is evolved and salt zinc chloride is formed as

Zn(s)+2HCl(aq)→ZnCl2​ (aq)+H2(g)

• The chemical element hydrogen is represented by the letter H and atomic number 1. The periodic table's lightest element is hydrogen, which has an average atomic weight of 1.008. In the universe, hydrogen is the most prevalent chemical, making up about 75% of all baryonic mass.
• Plasma hydrogen makes up the majority of non-remaining stars. Protium (name rarely used, symbol 1H), the most prevalent isotope of hydrogen, has one proton and no neutrons.
• When an acid interacts with a metal, hydrogen gas is released. For instance, zinc metal reacts with dil to produce zinc chloride and hydrogen.
