no this is a diatomic molecule and therefore does not have a charge.
Ca + Cl2 ----> CaCl Step 1) Ca + Cl2 ----> 2 CaCl There are 2 Cl's on the reaction side so you need 2 on the Product side Step 2) 2Ca + Cl2 ----> 2 CaCl There are now 2 Ca on the product side and you need 2 on the reactant side Voila!
Magnesium has a charge of +2 and Chloride has a charge of -1. In order to make magnesium chloride have a net charge of zero, there must be twice as much of the chloride ion than the magnesium ion. The ratio of magnesium to chloride is therefore 1:2. With this knowledge, we can write the chemical equation MgCl2.

H2 +Cl2---------------->2HCl Since H2 and Cl2 react in 1:1 mole ratio the number of moles of H2 reacting is equal to the number of moles of Cl2 which is equal to 0.213
For 2HCl(g) ==> H2(g) + Cl2(g) the Keq = [H2][Cl2]/[HCl]^2
-1, and since there is two, -2.
Chlorine does not have a charge. The element is Cl without a charge, and the molecule is Cl2 without a charge. The chloride ion has a charge of -1.
The chlorine ion is in group 7 so it has a charge of -1.

P4. It has 4 atoms compared to Cl2 having 2
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
Ca + Cl2 ----> CaCl Step 1) Ca + Cl2 ----> 2 CaCl There are 2 Cl's on the reaction side so you need 2 on the Product side Step 2) 2Ca + Cl2 ----> 2 CaCl There are now 2 Ca on the product side and you need 2 on the reactant side Voila!
H2 (g) + Cl2 (g) --> 2 HCl (g) 25.00 g HCl x 1 mol HCl x 1 mol Cl2 x 70.90 g Cl2 = 24.3 g Cl2 are needed. ................... 36.46 g HCl . 2 mol HCl .. 1 mol Cl2
The symbol for the cation (positive ion) is Fe2+. This is because that each Chlorine atom has a charge of -1 so to make the ions charge 0 overall, Fe must be 2+. Hope this helps!

This would be an oxidation-reduction reaction (or a single replacement reaction). On the left side of the equation, chlorine (Cl) has a negative charge, because it is bonded to sodium (Na). After it goes through the reaction, it is replaced by fluorine (F), making it Cl2 on the product side. As a atom that is not bonded, its charge is 0. The charge on Cl went from -1 to 0, so it is oxidized. The other anion, F, is reduced (the charge decreases from 0 to -1.
Thiosulfate: 2 S2O32- --> S4O62- + 2e-equivalency to:Chlorine: 1 Cl2 + 2e- --> 2Cl-31.6 ml * 0.141 mmol/ml S2O32- = 4.456 mmol S2O32-= 4.456 *(2 electron / 2 S2O32-) = 4.456 mmol (electrons) == 4.456 *(1 Cl2 / 2 electron) = 2.228 mmol Cl2 == 2.228 * 70.90 mg/mmol Cl2 = 158 mg == 0.158 g Chlorine
