Cl stands for chlorine or chloride as an periodic element
the subscript "2" means that each formula unit contains two atoms of the element that it follows. Cl2 is a molecule of diatomic chlorine.
P4+Cl2 P4+Cl2
Formula: Cl2
Cl2 + H2O = HOCl + HCl
ca + cl2 --> cacl2
There is no number for Cl2.Element Cl has 17 atomic number.
Cl2 (properly written the 2 would be a subscript - but that's tough to do here) represents a diatomic molecule of chlorine. At standard conditions, this is the form pure chlorine takes.
Balanced equation for Sodium and Chlorine is: 2Na + Cl2 --> 2NaCl
Cl2 is non polar.So there are london bonds.
Cl2 is a diatomic molecule.
Cl2
P4+Cl2 P4+Cl2
Formula: Cl2
At STP, Cl2 gas has a density of 0.0032g/mL. (Wikipedia article, "Chlorine") 0.30g Cl2 x (1mL Cl2/0.0032g) = 93.75mL Cl2
Na cl2
Cl2 stands for Chlorine.It is a gas of halogens.
You start with methane (CH4 ) and chlorine ( Cl2) and react them thus:- CH4 + Cl2 → CH3Cl + HCl CH3Cl + Cl2 → CH2Cl2 + HCl CH2Cl2 + Cl2 → CHCl3 + HCl
Cl2 + 2NaOH ----> NaCl + NaClO + H2O or Cl2 + 2OH- ----> Cl- + ClO- + H2O
