carbon dioxide
Limestone reacts with dilute hydrochloric acid to produce carbon dioxide gas, water, and calcium chloride salt. This reaction is a chemical reaction that results in the dissolution and breakdown of the limestone into its constituent parts.
It releases bubbles if carbon dioxide gas.
Ammonium chloride is formed when ammonia reacts with dilute hydrochloric acid.
Calcite is a mineral that reacts to dilute hydrochloric acid by fizzing or effervescing due to the release of carbon dioxide gas.
Dilute hydrochloric acid reacts with limestone to form calcium chloride, carbon dioxide, and water. This reaction causes the limestone to break down and dissolve, resulting in the release of gas bubbles and the formation of a calcium chloride solution.
When magnesium reacts with dilute hydrochloric acid, it gives off hydrogen gas.
When sodium bicarbonate reacts with dilute hydrochloric acid they produce carbon dioxide (CO2)
If the limestone rock fizzes when dilute acid is added, it indicates the presence of calcium carbonate in the rock. When calcium carbonate reacts with acid, it produces carbon dioxide gas, which causes the fizzing.
The temperature of the acid increases when zinc reacts with dilute hydrochloric acid because the reaction is exothermic, meaning it releases heat.
Nickel carbonate reacts with dilute hydrochloric acid to produce nickel chloride, carbon dioxide gas, and water.
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.
Gold is a metal that reacts steadily with dilute hydrochloric acid. This reaction produces gold chloride and hydrogen gas.
