Small amounts of chlorine gas can be made in the laboratory by putting concentrated hydrochloric acid in a flask with a side arm and rubber tubing attached. Manganese dioxide is then added and the flask stoppered. The reaction is not greatly exothermic. As chlorine is denser than air, it can be collected by placing the tube inside a flask where it will displace the air. Once full, the collecting flask can be stoppered.
HCl is Hydrochloric acid, it is formed with the combination of Hydrogen and Chlorine gases. It will react with nearly all alkali/bases as it is a strong acid.
Generally speaking, sugar mixed with HCL or hydrochloric acid turns black, bubbles, and expands. The two combined produce a exothermic reaction.
If you are talking about metals then magnesium, aluminium, zinc are some that will react readily
Calcite
Normally it doesn't but it will react with a mixture of nitric and hydrochloric acids called aqua regia.
Quartz
hydrochloric acid reacts with iron when it starts bubbling , magnesium reacts more though .
Gas, which dissolves in water extremely well and forms a Chlorine acid, one of the strongest acids. It reacts like all other strong acids with metals which are more electronegative than hydrogen. Also it reacts with bases and basic oxides. otherwise known as hydrochloric acid
Calcite
metal compound and chlorine

Among these calcium is highly reactive towards acids.

Hydrochloric acids are in stomach. Hydrochloric acid: HCl
Limestone is basically Calcium Carbonate(CaCO3). The metal part(Calcium) is the reactive part in it. It reacts with acids as well as bases. For example, it reacts with Hydrochloric acid to form calcium chloride whereas reacts with Ammonium hydroxide to form Calcium Hydroxide.
Lead is a moderately active metal. It dissolves slowly in water and in most cold acids. It reacts more rapidly with hot acids. It does not react with oxygen in the air readily and does not burn.
