no it was all wrong its fake
ironchloride and sulphuric acid
When calcium metal is added to a dilute solution of hydrochloric acid, a chemical reaction takes place in which calcium reacts with hydrochloric acid to produce calcium chloride and hydrogen gas. The balanced chemical equation is: Ca (s) + 2HCl (aq) -> CaCl2 (aq) + H2 (g)
You think probable to calcium carbonate.
Before dilute acetic acid is added to calcium carbonate, you would observe that the calcium carbonate is a white solid. There may be no visible reaction or bubbling occurring prior to the addition of the acid.
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.
When dilute hydrochloric acid (HCl) is added to calcium chloride (CaCl2), a double displacement reaction occurs. The products of this reaction are calcium chloride and water. Some of the calcium chloride may remain in solution while other parts may precipitate out, depending on the concentrations and quantities of the reactants.
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.
A base - sodium hydroxide.
solid is it?
Hydrogen gas.
Magnesium Chloride. MgCO3 +2HCl -----> MgCl2 + CO2 + H2O
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.
