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?
When sodium carbonate (Na2CO3) reacts with hydrochloric acid (HCl), the gas evolved is carbon dioxide (CO2). This reaction also produces water and sodium chloride (NaCl) as byproducts.
Give one test to identify HCL gas-?
One test to identify HCl gas is to pass the gas through damp blue litmus paper. HCl gas will turn the blue litmus paper red, indicating the presence of the gas.
What is the gas evolve in the reaction between hcl and caco3?
The gas evolved in the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is carbon dioxide (CO2). This reaction produces calcium chloride (CaCl2), water (H2O), and carbon dioxide gas as products.
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.

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?
Hydrochloric acid (HCl) is a colorless solution. It does not have a distinct color.
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.
What cause the effervescence during the reaction of HCl and Zinc?
Effervescence during the reaction of HCl and zinc is caused by the production of hydrogen gas. This gas is evolved as bubbles in the solution. The reaction is represented by the equation: Zn + 2HCl -> ZnCl2 + H2.
Which gas is evolved when KMnO4 reacts with H2C2O4?
The evolved gas is carbon dioxide (CO2).
