2NaCI is the chemical formula(there is no equation). The compound is called D-Glucosamine Sulfate.
The element Sodium (Na) The element Chlorine (Cl) The compound they make (NaCl) is called Sodium Chloride, commonly called table salt.
NaCl has not 2 in the formula unit.
NaCl
Fe + NaCl --> Na + FeClThis is called single replacement.
That refers to a mixture consisting of 2/100 of sodium chloride (salt) and 98/100 of something else (usually water).
The molar ratio of Cl2 to NaCl is 1:2, so for every 1 mole of Cl2, 2 moles of NaCl are produced. To find the amount of NaCl produced from 13g of Cl2, first calculate the number of moles of Cl2 using its molar mass, then use the mole ratio to determine the moles of NaCl, and finally convert to grams of NaCl.
If 2 moles of Na2CrO4 react completely, they will form the same number of moles of NaCl. This is because the mole ratio between Na2CrO4 and NaCl is 1:2. Therefore, 2 moles of Na2CrO4 will form 2 moles of NaCl.
The expected value for 'i' is 2 for NaCl because it dissociates into two ions (Na+ and Cl-) when dissolved in water. This means one formula unit of NaCl produces 2 ions in solution.
The formula unit of NaCl (sodium chloride) contain 2 atoms.

Two methods of preparation in laboratory:- 2 Na + Cl2 = 2 NaCl- NaOH + HCL = NaCl + H2O
