Fe and Cl are chemical elements situated in the periodic table.FeCl2 is a chemical compound.
No, just one covalent (single) bond: Cl-Cl
this can be trick balancing equations but this one is easy. the correct equation is CaCO3--> CaO+CO2. CaO plus CO2 does equal CaCO3 because you are adding the single Oxogen atom in CaO to the double Oxygen atom in CO2. basic maths makes it 1+2=3. Easy!!
The reaction is:Ag+ + Cl- = AgCl(s)Silver chloride is an insoluble, white, photosensitive precipitate.
An ion is always electrically charged.
no.

Cholride? Chlorine
CI2 is a covalent molecule. It consists of two chlorine atoms sharing a pair of electrons between them to form a single covalent bond.
Which compound has the highest melting point? Br2 I2 CI2 F2
The sum of all oxidation states in a compound is equal to the overall charge of the compound. This principle is derived from the fact that the total charge of a compound must be zero for a neutral compound.
The balanced equation for the reaction between KI and Cl2 to form KCl and I2 is: 2KI + Cl2 -> 2KCl + I2 This equation is already balanced.
It must be equal to the charge on the compound/ion
The molar mass of a compound is equal to 1 mol.
No, just one covalent (single) bond: Cl-Cl
The oxidation numbers in a neutral compound must equal zero. This is because the overall charge of a neutral compound is zero, so the sum of the oxidation numbers must balance out to zero.
