Because each side of the equation shows two chlorine atoms, two sodium atoms, and two iodine atoms, and these are the only atoms present.
The balanced equation for the reaction between calcium (Ca) and chlorine (Cl2) to form calcium chloride (CaCl2) is: 2Ca + Cl2 -> 2CaCl2
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
2KI + Cl2 = 2KCl + I2
The balanced equation is: Ca2Si + 3Cl2 → 2CaCl2 + SiCl4. This equation balances both the calcium and chlorine atoms on each side.
The balanced chemical equation for the reaction between chlorine (Cl2) and bromine (Br2) is: Cl2 + Br2 -> 2ClBr
The chemical equation is not balanced. It should be balanced as follows: H2 + Cl2 → 2HCl
HCl + NaOH = H2O + NaCl is already balanced.
The balanced equation is: 2MgBr2 + Cl2 → 2MgCl2 + Br2
The balanced equation for the reaction between calcium (Ca) and chlorine (Cl2) to form calcium chloride (CaCl2) is: 2Ca + Cl2 -> 2CaCl2
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.
H2 + Cl2 --> 2HCl
The balanced equation is as follows: 2HI + Cl2 --> 2HCl + I2
The balanced equation for the reaction between sodium (Na) and chlorine (Cl2) to form sodium chloride (NaCl) is 2Na + Cl2 -> 2NaCl. This equation is balanced because it has an equal number of each type of atom on both sides of the reaction arrow.
Cl2(g) + 2KI --> 2KCl(aq) + I2(s)
The balanced equation for Cl2 + 2KBr -> 2Br2 + 2KCl is balanced as it conserves the number of atoms on both sides of the reaction. Two moles of KBr reacts with one mole of Cl2 to produce two moles each of Br2 and KCl.
The balanced chemical equation for hydrogen reacting with chlorine to form hydrogen chloride is: H2 + Cl2 → 2HCl.
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
