Ca C O H & Cl
The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
hydrogen, chlorine, and iodine.
HCl is a compound of hydrogen and chlorine.
Calcium, carbon, and oxygen are the elements present in calcium carbonate, with the chemical formula CaCO3.
Calcium carbonate, CaCO3, has one calcium atom, one carbon atom, and three oxygen atoms, which adds up to five atoms.
HCI is Hydrogen (H), Carbon (C) and Iodine (I). Therefore, you have three elements in one molecule of HCI. Although, HCI is not balanced, so, that would actually be an ion, with negative charge.
