Ca displaces Mn
In the reaction MnO2 + 4HCl -> MnCl2 + Cl2 + 2H2O, manganese in MnO2 is getting oxidized from +4 to +2 (in MnCl2). Chloride ions in HCl are being reduced to chlorine gas (Cl2).
There is no element with that high a mass. Although, I believe you forgot the ., which should be "35.453" that is Cl.
"Ci" isn't a symbol on the periodic table.
Chlorine is the element that purifies water. Its symbol is Cl.
Since there is no element with the symbol An, there can be no possible answer.
MnCl2 contains one manganese (Mn) atom and two chlorine (Cl) atoms. To calculate the percent composition, divide the molar mass of each element by the molar mass of the compound and multiply by 100. The percent composition of Mn in MnCl2 is 25.41%, and the percent composition of Cl is 74.59%.
In MnCl2, the oxidation number of Mn is +2, as it is in the +2 oxidation state. The oxidation number of Cl is -1 each, as it is typically in the -1 oxidation state when bonded to metals such as manganese.
MnCl2 is an ionic compound. It is formed when a metal (Mn) bonds with a nonmetal (Cl) through ionic bonding, where electrons are transferred from the metal to the nonmetal.

CL is not an element; it is the symbol for chlorine, which is a chemical element with atomic number 17.

The element Cl is the gas chlorine.
Between manganese and chlorine alone, the most common compound is probably MnCl2. There may be others with manganese cations of different valence than +2.
The chemical formula for manganese is Mn and for chlorine is Cl. When these two elements combine, they can form various compounds such as manganese(II) chloride (MnCl2) or manganese(IV) chloride (MnCl4), depending on the oxidation state of manganese.
Chlorine is a chemical element.
