2008/2/23· May 17, 2012 A. It is basically an acid-base reaction, i.e., water and a salt are formed. So, one product would be CaCl 2 The other product is what is left over. 2HCl + CaCO 3 = CaCl 2 + H 2 CO 3. That product breaks down into water and carbon dioxide gas. So
Seven Things That Indie a Chemical Change Is …
Gas bubbles appear after a chemical reaction has occurred and the mixture becomes saturated with gas. The chemical change that creates the gas is completed after the gas bubbles leave the mixture. Examples of this type of reaction are when an antacid is dropped in a glass of water and begins to bubble or when boiling water bubbles.

Calcium metal reacts with water, evolving hydrogen gas at a rate rapid enough to be noticeable (unlike its sister magnesium) but not fast enough at room temperature to generate much heat. Part of the slowness of the calcium-water reaction results from the metal being partly protected by insoluble white calcium hydroxide .
