Which gas is evolved when few pieces of marble is added to dilute HCl?
When marble (calcium carbonate, CaCO3) is added to dilute hydrochloric acid (HCl), carbon dioxide gas (CO2) is evolved due to the reaction between the acid and the carbonate compound. This gas can be observed as bubbles coming out of the solution.
What are the gases evolved from Na2CO3 plus HCL?
Carbon Dioxide. H2CO3 <--> CO2 + H2O
Give one test to identify HCL gas-?
One way to test a gas to identify it as an HCL gas is to dip a glass rod in ammonia and place it in the gas. If a white smoke is produced, the gas is HCL gas.
What is the gas evolve in the reaction between hcl and caco3?
This is a metal and acid reaction. In these reactions, the gas produced is always hydrogen. The full balanced equation is: Mg (s) + 2 HCl (aq) --> MgCl2 (aq) + H2 (g) I hope this helps :)
Why is HCL gas not an acid but HCL aqueous an acid?
HCl gas is not an acid because it does not produce H+ ions in solution when dissolved in water. However, when HCl gas dissolves in water to form hydrochloric acid (HCl aqueous), it dissociates into H+ and Cl- ions, making it acidic.

When 5 ml of dilute HCL is added to a mixture of iron fillings and sulphur powder which gas is evolved?
When dilute hydrochloric acid (HCl) is added to a mixture of iron filings and sulfur powder, hydrogen gas (H₂) is evolved. The acid reacts with the iron filings, leading to the formation of iron chloride and the release of hydrogen gas. Sulfur does not react with hydrochloric acid under these conditions, so it does not contribute to the gas evolved.

Carbon Dioxide. H2CO3 <--> CO2 + H2O
Is HCl gas a mixture or a compound?
HCl gas is a compound.
Was gas evolved on action of hydrochloric acid on aluminium?
Yes,of course.As aluminium(Al)present above hydrogen(H) the reactivity series,it displaces hydrogen in hydrochloric(HCl) to form aluminium chloride(AlCl3) and as a result,hydrogen gas(H2) is evolved.

What color is HCl?
HCl is a colourless gas, with pungent odour. When dissolved in water to form hydrochloric acid , it remains colourless.
What is the balanced chemical equation when NH4Cl is heated?
When NH4Cl is heated, it decomposes into NH3 gas and HCl gas. The balanced chemical equation for this reaction is: NH4Cl(s) -> NH3(g) + HCl(g).
What is the chemical formula for hydrochloric gas?
The chemical formula for hydrogen chloride gas, also known as hydrochloric acid gas, is HCl.
Does fluorite react to HCL?
Yes, fluorite does react with hydrochloric acid (HCl) to produce hydrogen fluoride gas. This reaction can be observed by effervescence and the formation of a gas when fluorite is exposed to HCl.
