Because each side of the equation shows two chlorine atoms, two sodium atoms, and two iodine atoms, and these are the only atoms present.
ca + cl2 --> cacl2
Ca2Si + 4Cl2 >> 2CaCl2 + SiCl4
This equation is 2 Fe + 3 Cl2 -> 2 FeCl3.
2KI + Cl2 = 2KCl + I2
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
ca + cl2 --> cacl2
H2 + Cl2 --> 2HCl
HCl + NaOH = H2O + NaCl is already balanced.
The balanced equation is Cl2 + 2 KBr -> Br2 + 2 KCl.
No. This equation is not balanced and does not even represent any reaction. The equation for the actual reaction between elemental zinc and chlorine is: Zn + Cl2 => ZnCl2.
Balanced equation for Sodium and Chlorine is: 2Na + Cl2 --> 2NaCl
Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
Ca2Si + 4Cl2 >> 2CaCl2 + SiCl4
The balanced equation is as follows: 2HI + Cl2 --> 2HCl + I2
Cl2 + 2H = 2HCl
This equation is 2 Fe + 3 Cl2 -> 2 FeCl3.
The chemical equation CS2 + 2 Cl2 -> CCl4 + S2Cl2 is not balanced, because it shows four chlorine atoms on the left but six chlorine atoms on the right. The corresponding balanced equation is CS2 + 3 Cl2 -> CCl4 + S2Cl2.
