Science questions: Acid + Carbonate = what reaction? …

June 5, 2012. A. Lola, I think the question you are asking is how can you tell when a chemical reaction takes place. This is not always easy, because many reactions take place but do not show any visible signs of them happening. However, in the case of hydrochloric acid and calcium carbonate, the reaction is easy to see because the calcium carbonate starts to fizz and release a gas (carbon

Metal - Wikipedia

2019-4-23 · A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a

How does acid precipitation affect marble and …

How does acid precipitation affect marble and limestone buildings? Acid precipitation affects stone primarily in two ways: dissolution and alteration. When sulfurous, sulfuric, and nitric acids in polluted air react with the calcite in marble and limestone, the calcite dissolves.

2019-4-27 · Note: The first three in the table above produce hydroxides and the rest, if they react, produce oxides. The production of the hydroxide (alkali) can be tested by adding universal indior (UI) to the reaction vessel - UI changes from green to purple in the presence of these hydroxides. To test for the release of hydrogen gas, place a lighted splint over the reacting metal - if it ''pops'' then
