2Na + Cl2 -> 2NaCl
Cl2 + 2H = 2HCl

2 K + Cl2 = 2 KClOxygen is not needed.
In a chemical equation ,we must finish our chemical reaction with as many atoms of each element as when we started.the balanced chemical equation for the reaction of solid magnesium metal and barium chloride is given as .Mg + Bacl 2 -> Mgcl2 + Ba.
CuCl
Calcium + Chlorine --> Calcium Chloride Ca + Cl --> CaCl Balanced Equation: Ca + Cl2 --> CaCl2 Calcium has a 2+ charge, while chlorine has a 1- charge. Therefore you need two chlorine ions to balance the charges.
2K + Cl2 ---> 2KCl
H2 + Cl2 --------> 2HCl
2Na + Cl2 -> 2NaCl
Cl2 + 2H = 2HCl
2K+Cl2------->2KCl
The formula unit of sodium chloride (NaCl) contain sodium and chlorine.
Pmclg
2 K + Cl2 = 2 KClOxygen is not needed.
This equation is 2 Fe + 3 Cl2 -> 2 FeCl3.
2Fe + 3Cl2 ---> 2FeCl3 (iron(III) chloride) Fe +Cl2 -> FeCl2 (iron(II) chloride)
