The number 2 in the formula for magnesium chloride stands for the fact that two chloride ions, each with a charge of -1, must be present in the compound for each magnesium cation, with a charge of +2.
The formula of an ionic compound is most likely to be like the emperical formula for organic compounds. In this instance, the subscript 2 means that there are twice the number of chlorine atoms than the calcium atoms in an average sample.
It means there are 2 chloride atoms for every Mg atom.
That there are two bromide ions for every magnesium ion
MgCl2 is a compound with one magnesium atom and two chlorine atoms.

ionic
These are the ions and their charges: Ca+2 Cl-1The charges have to add up to zero, so one +2 calcium ion cancels out two -1 chlorine ions: Ca+2 Cl-1 Cl-1Simplify: CaCl2
The balanced chemical reaction of hydrochloric acid (HCl) reacting with calcium (Ca) is: 2HCl + Ca -> CaCl2 + H2
The chemical formula for calcium chloride is CaCl2.
No, CaCl2 is formed by an ionic bond. Calcium (Ca) is a metal and chlorine (Cl) is a non-metal, so they form an ionic bond where electrons are transferred from the calcium to the chlorine atoms.
Calcium chloride (CaCl2) is composed of one calcium ion (Ca2+) and two chloride ions (Cl-).
The 2 in CaCl2 means that there are two Cl (Chlorine) atoms in each formula unit.
No, CaCl2 is formed by an ionic bond. Calcium (Ca) is a metal and chlorine (Cl) is a non-metal, so they form an ionic bond where electrons are transferred from the calcium to the chlorine atoms.
The balanced chemical reaction of hydrochloric acid (HCl) reacting with calcium (Ca) is: 2HCl + Ca -> CaCl2 + H2
CaCl2 + 2H2O --> Ca(OH)2 + 2HCl
These are the ions and their charges: Ca+2 Cl-1The charges have to add up to zero, so one +2 calcium ion cancels out two -1 chlorine ions: Ca+2 Cl-1 Cl-1Simplify: CaCl2
Calcium chloride (CaCl2) is composed of one calcium ion (Ca2+) and two chloride ions (Cl-).
The formula for Calcium Chloride Trihydrate is CaCl2•3H2O. This means that each formula unit contains one calcium (Ca) atom, two chloride (Cl) ions, and three water (H2O) molecules.
The answer is TWO (2)Na2CO3 + CaCl2 --> 2 NaCl + CaCO3
CaCl2: Ca(OH)2 + HCl -------> CaCl2 + H2O
