When sulfur is added to hydrochloric acid (HCl), a gas may not be immediately visible because the reaction between sulfur and hydrochloric acid may be slow. The gas produced is hydrogen sulfide (H2S), which is a colorless gas and can be odorous at low concentrations. It may take some time for enough gas to accumulate to become visibly noticeable.

Why no gas is released when sulphur is added to dilute hcl?
When sulfur is added to dilute hydrochloric acid (HCl), no gas is typically released because sulfur is a non-reactive element and does not readily react with HCl to produce a gas. Sulfur can only react with strong oxidizing agents, such as concentrated nitric acid or hot concentrated sulfuric acid, to release sulfur dioxide gas.
Why no gas is released if sulphur is added to dilute hydrochloric acid?
When sulfur is added to dilute hydrochloric acid, it reacts with the acid to form hydrogen sulfide gas. This gas is colorless and has a strong odor of rotten eggs. The reaction occurs slowly because of the low reactivity of sulfur with hydrochloric acid, resulting in a delayed release of gas.
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 happens if aluminum is added in dilute hcl?
When aluminum is added to dilute hydrochloric acid (HCl), a chemical reaction occurs. The aluminum reacts with the HCl to form aluminum chloride and hydrogen gas. The reaction is exothermic and produces bubbles of hydrogen gas as it proceeds.
What gas is formed when HCl is added to Na2S?
When HCl is added to Na2S, hydrogen sulfide gas (H2S) is formed. This gas has a characteristic rotten egg smell and is toxic in high concentrations.

What happens when water is added to the gas jars in which sulphur was burnt?
When water is added to the gas jars in which sulphur was burnt, a chemical reaction occurs. The sulphur dioxide gas produced from burning sulphur reacts with the water to form sulphurous acid (H2SO3). This reaction results in the formation of a colorless solution with acidic properties.
What are the ingredients for poison gas?
Sulphur dioxide + ethylene --> mustard gas orthiodiglycol + a chlorinating agent (conc. HCl or some phosphorus trichloride) --> mustard gas.

Which gas is produced when Mg is added to HCl?
h2
How can sulphur dioxide be removed from flue gas by wet scrubbing?
Sulphur dioxide can be removed from flue gas by wet scrubbing using a scrubbing solution such as a slurry of limestone in water. The sulphur dioxide reacts with the alkaline solution to form calcium sulfite or sulfate, which can then be separated from the gas stream. The scrubbed gas is then released into the atmosphere with reduced sulphur dioxide levels.
When CaCo3 is added to Hcl what is formed?
When CaCO3 is added to HCl, carbon dioxide gas (CO2) is formed along with calcium chloride (CaCl2) and water (H2O) as products.
Is HCl gas a mixture or a compound?
HCl gas is a compound.
What is formed when sulphur burns in oxegyen?
S + O2 = SO2 You get Sulphur Dioxide (It smells like burnt matches and is a poisonous gas). Lots of it is released by volcanoes.
