Description : What Mass Of Calcium Carbonate Is Needed For Complete Reaction With The HCl In 2HCl(aq) plus CaCO 3 (s) CaCl 2 (aq) plus H 2 O(l) plus CO 2 (g)?
Last Answer : Need answer
Description : Why are Calcium Carbide (CaC 2 ), Carbon monoxide (CO), Carbon dioxide (CO 2 ), Hydrogen cyanide (HCN) and calcium carbonate (CaCO 3 ) classified as inorganic compounds through they contain carbon?
Last Answer : These compounds contain only one or two carbon atoms per formula unit and contain no carbon-carbon (C-C) bonds or carbon-hydrogen bonds. Hence they are classified as inorganic compounds.
